SURFLIB_REMOVE_DC_FROM_EXP - Remove linear baseline from each exposure

Description:

This routine takes a data array. It then removes a DC offset (either the mean or the median derived from the scan) from each scan.

Invocation:

CALL SCULIB_REMOVE_DC_FROM_EXP(DORLB, N_EXPOSURES, N_INTEGRATIONS, N_MEASUREMENTS, METHOD, DEM_PNTR, N_BOL, N_POS, IN_DATA, IN_QUALITY, SAMPLE_DX, CHOP_THROW, OUT_DATA, OUT_QUALITY, BADBIT, STATUS)

Arguments:

DORLB = LOGICAL (Given)

control whether we are subtracting the baseline (TRUE) or storing the basline (FALSE)

N_EXPOSURES = INTEGER (Given)

maximum number of exposures per integration

N_INTEGRATIONS = INTEGER (Given)

number of integrations in the observation

N_MEASUREMENTS = INTEGER (Given)

number of measurements in the observation

METHOD = CHAR (Given)

Removal method. MEDIAN or MEAN supported.

DEMOD_POINTER (N_EXPOSURES, N_INTEGRATIONS, N_MEASUREMENTS)

= INTEGER (Given) array pointing to start and finish of scans in IN_DATA

N_BOL = INTEGER (Given)

the number of bolometers for which data was taken

N_POS = INTEGER (Given)

the number of positions measured in the scan

IN_DATA (N_BOL, N_POS) = REAL (Given)

the measured data

IN_VARIANCE (N_BOL, N_POS) = REAL (Given)

the measured variance

IN_QUALITY (N_BOL, N_POS) = BYTE (Given)

the quality on IN_DATA

OUT_DATA (N_BOL, N_POS) = REAL (Returned)

the data with baseline removed

OUT_VARIANCE (N_BOL, N_POS) = REAL (Given)

the output variance

OUT_QUALITY (N_BOL, N_POS) = BYTE (Returned)

the quality on OUT_DATA

BADBIT = BYTE (Given)

bad bit mask

STATUS = INTEGER (Given and Returned)

Global Status value
