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
of Section 2.1 except you should invoke
instead of
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
Section 4.2.2 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.
