When running ORAC-DR, you may see error messages stating "Problem reading engine version information". To eliminate this message download this file and save it to $STARLINK_DIR/manifests. If you do not have write permissions to this directory or cannot otherwise update this file, don't worry. The error messages are harmless and have no effect on data.
You should now be able to run ORAC-DR. To do so, type
$ORAC_DIR/etc/oracdr_acsis < utdate >
You need to provide the utdate when running up ORAC-DR.
setenv ORAC_DATA_IN < path to directory where data is kept >
setenv ORAC_DATA_OUT < path to directory where reduced data will go >
oracdr -list 20:23,26:29 -batch -log xf -nodisplay
The next two commands tell ORAC-DR where to find the data to process and where to put the processed data. If you want to work with the raw and processed data in the same directory then you may as well run the pipeline from that directory and provide `pwd` as the path in these two commands.
The last command sets the pipeline running with the following parameters:
-list list of observation numbers
The more data that go into a cube the better, since the improved baselines are estimated from the coadded group file, and are then applied to the individual cubes. This results in improved single observation products (labelled as _reduced in the output directory). However, the current version of ORAC-DR does not then coadd the resultant improved single observation cubes into an improved coadded group product. This can be done manually using the KAPPA wcsmosaic command. For example,
-batch runs in batch mode (quicker)
-log xf writes log to x-term and to a file
-nodisplay suppresses the display of graphics (quicker)
wcsmosaic in="a*_01_reduced*" out=final_group
