scopesim_templates.stellar.stellar.star_field(n, mmin, mmax, width, height=None, filter_name='V', ra=0, dec=0, **kwargs)#

Create a super basic field of stars with random positions and brightnesses.

Parameters:

  • n (int) – number of stars

  • mmin (astropy.Quantity, float) – [mag, Jy] minimum and maximum flux amplitudes of the population in u.mag (u.ABmag) or u.Janksy where u is for astropy.units. If mmin and mmax are floats, Vega magnitudes are assumed

  • mmax (astropy.Quantity, float) – [mag, Jy] minimum and maximum flux amplitudes of the population in u.mag (u.ABmag) or u.Janksy where u is for astropy.units. If mmin and mmax are floats, Vega magnitudes are assumed

  • width (float) – [arcsec] width of region to put stars in. if height=None, height=width

  • height (float) – [arcsec] width of region to put stars in. if height=None, height=width

  • filter_name (str) – For scaling the stars. Use either common names or Spanish-VO identifiers.

  • ra (float or str) – RA of the center of the field (not used at the moment).

  • dec (float or str) – DEC of the center of the field (not used at the moment).

  • parameters (Additional)

  • ---------------------

  • x (lists, arrays) – [arcsec] The positions of the stars can be overridden by specifying the coordinates. The lists must contain N values

  • y (lists, arrays) – [arcsec] The positions of the stars can be overridden by specifying the coordinates. The lists must contain N values

Returns:

stars – A Source object with a field of stars that can be fed into the method: <OpticalTrain>.observe()

Return type:

scopesim.Source object
