name : string
pixelscale : float
Pixel scale in arcsec/pixel
fov_pixels, fov_arcsec : float
The field of view may be specified either in arcseconds or by a number of pixels. Either is acceptable
and the pixel scale is used to convert as needed. You may specify a non-square FOV by providing two elements in an iterable.
Note that this follows the usual Python convention of ordering axes (Y,X), so put your desired Y axis size first.
oversample : int
Oversampling factor beyond the detector pixel scale
offset : tuple (X,Y)
Offset for the detector center relative to a hypothetical off-axis PSF. Specifying this lets you
pick a different sub-region for the detector to compute, if for some reason you are computing a small
subarray around an off-axis source. (Has not been tested!)
