Processing UKIRT data obtained before 2000 August

Before the introduction of ORAC on 2000 August 1, UFTI raw data were in FITS format, IRCAM data had a different naming convention, and there were different default paths for $ORAC_DATA_IN and $ORAC_DATA_OUT. IRCAM's NDFs were copied to $ORAC_DATA_OUT, and UFTI's raw FITS files were converted to NDFs in that directory.

To process data from this era, follow the instructions for using the pipeline except you should invoke

 % oracdr_<instrument>_old <date>
instead of
 % oracdr_<instrument> <date>
to set up the necessary environment variables. The rest is the same.

You can use modern jitter-generic recipes too, provided they know how many frames to process. The easiest way to do that is make your own copy of the recipe and set the number frames as an argument to the steering primitive. See here for details.

The standard raw and reduced directories prior to 2000 August were
<instrument>_data/YYYYMMDD/raw/, and <instrument>_data/YYYYMMDD/reduced/ respectively, where <instrument> was either ufti or ircam.

Details of the former naming convention for IRCAM frames is given under the ``Output Data'' headings in the reference section.
