BPASSPRM
Type: Adverb (Array(11))
Use: Bandpass calibration control parameter array.
Tasks:
BPASS.....Computes spectral bandpass correction table
CPASS.....Computes polynomial spectral bandpass correction table
BPASSPRM use - see task helps for details
(1) if > 0 use only the autocorrelation data.
(2) print level.
(3) If > 0 do not divide data by source model
(4) If > 0 store phases only in the BP table.
(5) Divide by 'channel 0' control:
0 -> divide by channel 0 amp and phase each time
-1 -> divide by channel 0 phase only each time
1 -> do no division by channel 0 at each time
(6) amp closure error limit - print channels averaging
over this if (2) > 0
(7) phase closure error limit print channels averaging
over this if (2) > 0
(8) > 0 => scalar average amplitudes
(9) > 0 => interpolate over flagged channels if poss.
(10) 0 => no deliberate normalization after solutions
found.
1 => normalize amplitudes using all channels
2 => normalize amplitudes using ICHANSEL channels
3 => normalize amplitudes and zero average phase
using ICHANSEL channels
4 => normalize amplitudes and zero average phase
using all channels
5 => normalize amplitudes and zero average phase
using ICHANSEL channels - normalizes power
(square of BP function) not function itself
6 => normalize amplitudes and zero average phase
using all channels - normalizes power (square of
BP function) not function itself
(11) > 0 solution weights are independent of channel
<=0, > -1.5 weights scaled by amplitude**2
< -1.5 weights scaled by 1 / amplitude**2
