Type: Adverb (Real array(4,20))
Use: Spectral index S as a function of polarization (I, Q, U, V) and
source number where
log(T(f)/T(f0) = S * log(f/f0)
PCAL......Computes antenna-based polarization leakage terms and,
optionally, also determines source polarization (Q, U, V).
SPECPARM sets spectral indices to be used in applying
source models including the total intensity which is used
while fitting for source Q and U.
RLCAL.....Determines instrumental right-left phase versus time
(a self-cal). SPECPARM gives the spectral indices to
be used with PMODEL.
