Task RDI solves the atmospheric calibration observations (with
or without cold load measurement), to obtain the correction factors
. There is one such
coefficient for each side band of each receiver in each antenna. The
standard atmospheric model is used, but the data is interpolated out of a
pre-computed table to save computing time (the table name is the logical
name GAG_ATMOSPHERE which should translate to COMP$DISK:[CONTROL.OBS]ATM-BURE-VAX.BIN). The new parameters are
stored in the data files in the new header section named ``Atmospheric
monitor''. This is currently implemented.
At the same time a default is set for the quantity
above: it is the measured atmosphere emission at the time of the last
calibration. This will have to be refined by the command MONITOR.
