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)

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
