m52snr¶
- rubin_sim.maf.utils.m52snr(m, m5)¶
Calculate the SNR for a star of magnitude m in an observation with 5-sigma limiting magnitude depth m5. Assumes gaussian distribution of photons and might not be strictly due in bluer filters. See table 2 and equation 5 in astroph/0805.2366.
- Parameters:
- mfloat or numpy.ndarray
The magnitude of the star
- m5float or numpy.ndarray
The m5 limiting magnitude of the observation
- Returns:
- float or numpy.ndarray
The SNR
