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

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
