simulate_crs¶
- romanisim.cr.simulate_crs(image, time, flux=None, area=None, conversion_factor=None, pixel_size=None, pixel_depth=None, rng=None, seed=47)¶
Adds CRs to an existing image.
- Parameters:
- image2-d array of floats
The detector image with values in units of electrons.
- timefloat
The exposure time, units of s.
- fluxfloat
Cosmic ray flux, units of cm^-2 s^-1. Default value of 8 is equal to the value assumed by the JWST ETC.
- areafloat
The area of the WFI detector, units of cm^2.
- conversion_factorfloat
The convert from eV to electrons, assumed to be the bandgap energy, in units of eV / electrons.
- pixel_sizefloat
The size of an individual pixel in the detector, units of micron.
- pixel_depthfloat
The depth of an individual pixel in the detector, units of micron.
- rngnp.random.Generator
Random number generator to use
- seedint
seed to use for random number generator
- Returns:
- image2-d array of floats
The detector image, in units of electrons, updated to include all of the generated cosmic ray hits.
