SCULIB_CORRECT_EXTINCTION - correct bolometers for sky opacity

Description:

This routine corrects bolometer data for the effect of sky opacity. It does this by calculating the airmass of the point that each bolometer was looking at, then multiplying the data by exp (airmass $*$ TAUZ). Bolometers with bad data quality will be ignored.

Invocation:

CALL SCULIB_CORRECT_EXTINCTION (SIZE_BOL, N_BOL, BOL_DATA, BOL_VARIANCE, BOL_RA, BOL_DEC, LST, LAT_OBS, TAUZ, STATUS)

Arguments:

SIZE_BOL = INTEGER (Given)

dimension of arrays

N_BOL = INTEGER (Given)

used size of arrays

BOL_DATA (SIZE_BOL) = REAL (Given and returned)

bolometer data

BOL_VARIANCE (SIZE_BOL) = REAL (Given and returned)

variance on BOL_DATA

BOL_RA (SIZE_BOL) = DOUBLE PRECISION (Given)

apparent RA of bolometer (radians)

BOL_DEC (SIZE_BOL) = DOUBLE PRECISION (Given)

apparent dec of bolometer (radians)

LST = DOUBLE PRECISION (Given)

sidereal time (radians)

LAT_OBS = DOUBLE PRECISION (Given)

latitude of observatory (radians)

TAUZ = REAL (Given)

the zenith sky opacity

STATUS = INTEGER (Given and returned)

global status
