star_grid¶
-
simcado.source.star_grid(n, mag_min, mag_max, filter_name='Ks', separation=1, spec_type='A0V')[source]¶ Creates a square grid of A0V stars at equal magnitude intervals
- Parameters
- nfloat
the number of stars in the grid
- mag_min, mag_maxfloat
[vega mag] the minimum (brightest) and maximum (faintest) magnitudes for stars in the grid
- filter_namestr
any filter that is in the SimCADO package directory. See
simcado.optics.get_filter_set()- separationfloat, optional
[arcsec] an average speration between the stars in the grid can be specified. Default is 1 arcsec
- spec_typestr, optional
the spectral type of the star, e.g. “A0V”, “G5III”
- Returns
- source
simcado.Source
- source
Notes
The units of the A0V spectrum in
sourceare [ph/s/m2/bin]. The weight values are the scaling factors to bring a V=0 A0V spectrum down to the required magnitude for each star.
