calc_sky_counts_per_pixel_for_m5

rubin_sim.phot_utils.calc_sky_counts_per_pixel_for_m5(m5target, total_bandpass, phot_params, fwhm_eff=None)

Calculate the number of sky counts per pixel expected for a given value of the 5-sigma limiting magnitude (m5)

The 5-sigma limiting magnitude (m5) for an observation is determined by a combination of the telescope and camera parameters (such as diameter of the mirrors and the readnoise) together with the sky background.

Parameters:

m5targetfloat

the desired value of m5

total_bandpassBandpass

A bandpass object representing the total throughput of the telescope (instrumentation plus atmosphere)

phot_paramsPhotometricParameters

A photometric parameters object containing the photometric response information for Rubin

fwhm_efffloat

fwhm_eff in arcseconds

Returns:

sky_counts_targetfloat

the expected number of sky counts per pixel
