with BPASS, have fluxes reduced by a factor of about 1000.0
Here below I report the parameter set I used for running BPASS:
AIPS 1: BPASS Task to generate a "Bandpass" (BP) table.

AIPS 1: autocorrelation data.
AIPS 1: 2: print level - see help
AIPS 1: 3: If > 0 do not divide data
AIPS 1: by source model
AIPS 1: 4: If > 0 store phases only
AIPS 1: in the BP table.

AIPS 1: increment and IF to be used
AIPS 1: to select channels to sum to
AIPS 1: find a 'channel 0'. If all
AIPS 1: 0, range set to inner 75% of
AIPS 1: observing band.
AIPS 1:

Am I setting wrongly the BPASS parameters ?
Thanks for your help.
ciao,
