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:
- m5target
float
the desired value of m5
- total_bandpass
Bandpass
A bandpass object representing the total throughput of the telescope (instrumentation plus atmosphere)
- phot_params
PhotometricParameters
A photometric parameters object containing the photometric response information for Rubin
- fwhm_eff
float
fwhm_eff in arcseconds
- m5target
- Returns:
- sky_counts_target
float
the expected number of sky counts per pixel
- sky_counts_target
