This notebook shows a simplified use case utilizing a dummy set of randomly generated particle data. It is by default set to simulate a catalog of stars with Gaia DR2 astrometry & photometry, but you may change the parameters defined below to your liking. In short, the pipeline is accessible via the class Ananke, which method run can eventually be called after creation of an Ananke object to run the full ananke pipeline. The method run is designed to returns the catalog in the form of an Output object of the submodule galaxia_ananke which can be used as a vaex dataframe.

Below are the packages that this notebook must import:

import numpy as np
import ananke as an
an.__version__

'0.5.0'

We define here some dummy input data. Ananke has a method make_dummy_particles_input to produce such data in a dictionary formatted output. Below we show how to call it and the keys that compose that dictionary.

np.random.seed(0)
p = an.Ananke.make_dummy_particles_input()
p.keys()

dict_keys(['pos3', 'vel3', 'mass', 'age', 'feh', 'helium', 'carbon', 'nitrogen', 'oxygen', 'neon', 'magnesium', 'silicon', 'sulphur', 'calcium', 'alpha', 'parentid', 'partitionid', 'dform', 'id', 'log10_NH'])

The input data must be formatted as a dictionary of equal-length arrays. The dictionary must have the following entries:

• key pos3: particle position coordinates in \(kpc\) (shape Nx3)

• key vel3: particle velocity coordinates in \(km.s^{-1}\) (shape Nx3)

• key mass: particle stellar mass in solar masses

• key age: particle log10 stellar age in years

• key feh: particle stellar metallicity [Fe/H] in dex relative to solar

Additionally, the following entries can optionally be added:

• key parentid: index to give to the parent particle

• key id: additional index to classify the parent particle

• key log10_NH: log10 hydrogen column densities between Observer position and particle in \(cm^{-2}\) - must be provided to estimate extinctions

• key dform: particle formation distance

• keys helium, carbon, nitrogen, oxygen, neon, magnesium, silicon, sulphur, calcium: particle various chemical abundances [X/H]

• key alpha: particle alpha chemical abundances [Mg/Fe]

Ananke will compute the phase space densities that are used to determine particle smoothing lengths, but one can include pre-computed densities with the following entries:

• key rho_pos: particle density in position space in \(kpc^{-3}\)

• key rho_vel: particle density in velocity space in \(km^{-3}.s^{3}\)

At any time, you may access this format via the helper of the Ananke.make_dummy_particles_input method using

help(an.Ananke.make_dummy_particles_input)

We define below some parameters for Ananke such as

• the observer position observer

• the shell of particles to mask rshell

• the sampling factor fsample

• the photometric system of choice photo_sys (in our case Gaia DR2)

• the CMD cmd_magnames and its box limits cmd_box

D = 200 # *units.kpc

observer = np.nan*np.ones(3)
while not np.linalg.norm(observer)<1:
    observer = 2*np.random.rand(3)-1

observer *= D/np.linalg.norm(observer)

rshell = [0, 2*D]

fsample = 0.01

photo_sys = 'padova/GAIA__DR2'

cmd_magnames = {'magnitude': 'G',
                'color_minuend': 'Gbp',
                'color_subtrahend': 'Grp'}

cmd_box = {
           'abs_mag_lim_lo': -1000,
           'abs_mag_lim_hi': 1000,
        #    'app_mag_lim_lo' : -1000,
           'app_mag_lim_hi': 30,
        #    'color_lim_lo' : -1000,
        #    'color_lim_hi' : 1000
           }

For more details regarding these parameters and more, you may consult the docstring associated to the class Ananke via the lines:

help(an.Ananke.__init__)

or

help(an.Ananke)

Note that among those are 3 special parameters, d_params, e_params and err_params, which receive dictionaries of subparameters to configure the sub-steps of the pipeline corresponding respectively to the phase space density estimation, the extinction mapping and the instrument error modeling. Each have further documentation that can be accessed calling the following methods:

an.display_density_docs() for d_params

an.display_extinction_docs() for e_params

an.display_errormodel_docs() for err_params

We show below how to create the Ananke pipeline object before calling run, using the parameters we defined above.

name = 'sim'
ananke = an.Ananke(p, name, fsample=fsample,
                   observer=observer, rshell=rshell,
                   photo_sys=photo_sys, cmd_magnames=cmd_magnames,
                   **cmd_box)

As mentioned above, the Ananke method run runs the pipeline once it has been created. Some additional parameters can be provided to this method, which are listed in its docstring (accessible by calling help(ananke.run)). Those include:

• input_dir, output_dir, i_o_dir - Optional arguments to specify paths for the directories where ananke should generate input and output data. If the i_o_dir keyword argument is provided, it overrides any path given to the input_dir and output_dir keyword arguments.

• k_factor – Scaling factor applied to the kernels lengths to adjust all the kernels sizes uniformly. Lower values reduces the kernels extents, while higher values increases them. Default to 1 (no adjustment).

• surveyname – Optional name Galaxia should use for the output files. Default to 'survey'.

• n_jobs – Number of independent catalog generations ran in parallel. Default to 1.

• verbose – Verbose boolean flag to allow pipeline to print what it’s doing to stdout. Default to True.

• rand_seed – Seed to be used by Galaxia’s pseudorandom number generator. Default to 17052

• nstart – Index at which to start indexing synthetic stars. Default to 0 For our example however, we will use the method as it is.

Warning

Some of the run method parameters are currently not properly implemented, using them may lead to unexpected results

The output is saved as a vaex dataframe, with its columns organized in alphabetical order. The photometry is stored in columns that are named according to their associated photometric system and filter name. The keys are in the lowercase format photosys_filtername where photo_sys is the photometric system and filtername is the filter name. In this example, the apparent photometry in filters gbp, grp & g of the Gaia DR2 system (identified as GAIA__DR2 in Galaxia) are respectively under keys gaia__dr2_gbp, gaia__dr2_grp & gaia__dr2_g. Beside these, the columns include:

• key A_0 for the reference extinction which extinction coefficients are based on (at \(\lambda = 550 \, nm\) in the case of Gaia DR2)

• key A_{filter_name} for the extinction value in each filter designated by filter_name (here A_gaia__dr2_g, A_gaia__dr2_gbp & A_gaia__dr2_grp)

• key E(B-V) for the reddening index

• key age for the \(log_{10}\) stellar age in years

• key alpha, calcium, carbon, helium, magnesium, neon, nitrogen, oxygen, silicon, sulphur for the various chemical abundances as given as input

• key dec, ra for the astrometric declination and right ascension celestial coordinates in degrees

• key dform for the formation distance as given as input

• key dmod for the distance modulus

• key feh for the stellar metallicity [Fe/H] in dex relative to solar

• key {filter_name}_Intrinsic for the intrinsic stellar photometry in each filter designated by filter_name (here gaia__dr2_g_Intrinsic, gaia__dr2_gbp_Intrinsic & gaia__dr2_grp_Intrinsic)

• key glat, glon for the astrometric galactic latitude and longitude celestrial coordinates in degrees

• key grav for the \(log_{10}\) surface gravity in CGS units

• key log10_NH for the \(log_{10}\) hydrogen column density between Observer position and star in \(cm^{-2}\)

• key lum for the stellar luminosity in solar luminosities

• key mact, mtip, smass for respectively the current stellar mass, the mass of that same star at tip of giant branch for its given age & metallicity and its stellar mass on zero-age main sequence, all in solar masses

• key mub, mudec, mul, mura for the astrometric proper motions, respectively in the direction of the galactic latitude, declination, galactic longitude and right ascension, all in milliarcseconds per year

• key parentid for the parent particle index as given as input

• key partid for the flag that identifies stars that are not central relatively to their parent particle

• key pi for the star parallax in milliarcseconds

• key px, py, pz for the star position cartesian coordinates in \(kpc\) relative to the Observer’s position

• key rad for the star distance to the Observer in \(kpc\)

• key satid for the index id the population the parent particle is part of

• key teff for the star effective temperature in Kelvin

• key vr for the star astrometric radial velocity in \(km.s^{-1}\)

• key vx, vy, vz for the star velocity cartesian coordinates in \(km.s^{-1}\) relative to the Observer’s velocity

Additionally, astrometric and photometric quantities X all have associated columns identified as:

• key {X}_Sig for the standard error on the quantity X

• key {X}_Err for the actual drawn gaussian error on the quantity X

Taking the photometry as an example of the latter, the standard errors are stored under gaia__dr2_g_Sig, gaia__dr2_gbp_Sig & gaia__dr2_grp_Sig, while the drawn errors are under gaia__dr2_g_Err, gaia__dr2_gbp_Err & gaia__dr2_grp_Err.
