make_one_psf_epsf

romanisim.psf.make_one_psf_epsf(sca, filter_name, wcs=None, pix=None, chromatic=False, extra_convolution=None, date=None, **kw)

Make a PSF profile for Roman at a specific detector location using CRDS reftype epsf

Parameters:

scaint

SCA number

filter_namestr

name of filter

wcscallable (optional)

function giving mapping from pixels to sky for use in computing local scale of image for stpsf PSFs

pixtuple (float, float)

pixel location of PSF on focal plane

chromaticbool

Create a multiwavelength-based psf.

extra_convolutiongalsim.gsobject.GSObject or None

Additional convolution to add to PSF

dateastropy.time.Time or None

Date of simulation. If None, current date is used. Needed for psftype=’epsf’ to choose the appropriate epsf reference.

**kwdict

Additional keywords passed to galsim.roman.getPSF or stpsf.calc_psf, depending on whether stpsf is set.

Returns:

profilegalsim.gsobject.GSObject

galsim profile object for convolution with source profiles when rendering scenes.
