ISAAC Preliminary Conversion

Since ORAC-DR as yet cannot cope with ISAAC 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 earliest file has observation number 1, and the observation number increments for each FITS file in time order. The script copes with file names in either the raw or archive nomenclature. 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 of the calibration and target files for a given night in the same directory.
