ISAAC and NACO Preliminary Conversion

Since ORAC-DR as yet cannot cope with ESO file naming, which uses the UT epoch instead of a sequence number, there is a special C-shell script which must be invoked once, normally before the first ORAC-DR initialisation. If you enter

 % isaac2oracdr

in a directory containing ISAAC FITS files, the command converts them into NDFs with names adhering to the UKIRT convention. The prefix is isaac. The earliest file has observation number 1, and the observation number increments for each FITS file in time order. The script copes with files names in either the raw or archive nomenclature. It also writes observation and group number headers to assist ORAC-DR. It copes with data from more than one night in a given directory, assigning each night its own sequence of observation numbers; and it uses a common UT date for observations in a single night spanning midnight UT. You should put all both the calibration and target files for a given night in the same directory.

Likewise in a directory of NACO FITS files, you should first enter

 % naco2oracdr

to create a set of NDF files whose names adhere to the UKIRT convention with a naco prefix.
