snrToPhaseRmsDegrees
Implements the formulas in the Synthesis Imaging textbook (Volume 1) that convert from S/N to rms phase:
7-51 (for snr < 1.837) and 7-52 (for snr > 1.837).
Usage:
au.snrToPhaseRmsDegrees(snr)
Example:
CASA <3>: au.snrToPhaseRmsDegrees(1)
Out[3]: 64.33233523179355
CASA <4>: au.snrToPhaseRmsDegrees(10)
Out[4]: 5.729577951308233
