SCULIB_SUB_TAUZ

get tauz appropriate for each sub-instrument

Description:

This routine finds the zenith sky optical depth appropriate for the filter in front of each sub-instrument being used. If it cannot find an optical depth for the required filter the routine will output a warning message and return an optical depth of 0.0.

The times and dates at which the optical depths were measured are also returned. If the optical depth for the required filter cannot be found then the date will be that at which the routine is run.

Invocation

CALL SCULIB_GET_TAUZ (N_SUBS, SUB_FILTER, N_SKY, SKY_FILTER, SKY_TAUZ, SKY_DAY, SUB_TAUZ, SUB_DAY, STATUS)
