SURFLIB_REMOVE_DC_VIA_SECT - Remove median baseline from each exposure

Description:

This routine takes a data array and removes a DC offset from each scan. The DC level is the median of the data specified in the SCUBA section for that particular integration. The same level is removed for each scan of an integration with a different value for each bolometer.

Invocation:

CALL SCULIB_REMOVE_DC_FROM_EXP(DORLB,N_SPEC,SECTION,USE_SECT,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_SPEC = INTEGER (Given)

Number of sections specified

SECTION ( N_SPEC ) = CHAR (Given)

Array of section specifications

USE_SECT = LOGICAL (Given)

Is this an inverse section

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

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
