if true, wait until all stars are generated to calculate kinematics
- chunk_sizeint
number of stars to generate per chunk to limit memory use
- ref_bandstr
primary photometric filter for catalog
position max_mass : float
maximum allowed stellar mass

- generate_stars(radii, missing_stars, mass_limit, do_kinematics, props)
- generate_star_at_location(position, props, min_mass=None, max_mass=None)
generates stars at the given positions
- get_evolved_props(m_init: numpy.ndarray, met: numpy.ndarray, age: numpy.ndarray, props: Set, **kwargs) Tuple[numpy.ndarray, Dict, numpy.ndarray]
evolve the stars using a list of evolution classes given by self.evolution each evolution class have a min and max mass range where it should be used. the used class are ranked by the order in the list.
Parameters
- m_initndarray [Msun]
list of initial masses for all stars
- metndarray [Fe/H]
list of metallicities for all stars
- agendarray [Gyr]
list of ages for all stars
- propsndarray
set of properties which should be interpolated
- kwargs :
keywords passed to the evolutionary process
Returns
- mag: ndarray
list of the main magnitude
- s_track: dict
collection of ndarratys for each of the interpolated properties
- inside_grid: ndarray
used to check if the the star is inside the isochrone grid
