In order to configure the ORAC-DR SCUBA data reduction pipeline a setup command, oracdr_scuba, is provided. Assuming you are running the command from the Unix TC-shell1 this command sets all the environment variables and command aliases required to run the pipeline. The UT date of the observations can be specified by supplying an argument to the command, if not specified the current UT date is assumed:
% oracdr_scuba 19990703
In order for the startup script to be configured to read the input data, an environment variable must be set which points to the directory containing the UT date directory. For example, if your data is in directory /mydata/19991012 the following is required:
% setenv ORAC_DATA_ROOT /mydata % oracdr_scuba 19991012
If ORAC_DATA_ROOT is not set then the current directory will be assumed unless the script is run at the Joint Astronomy Centre. With this variable unset when run at the Joint Astronomy Centre the input data directory will be configured to point to the actual SCUBA archive data directory.
When run, this command should list information detailing the current setup. Hopefully, it should be obvious at this point whether something has gone wrong. Here is an example for the JAC:
% oracdr_scuba 20000127 ORAC Data Reduction Pipeline -- (ORAC-DR Version 1.0-0) Configured for instrument SCUBA Type "oracdr -h" for usage Type 'showme sun231' to browse the hypertext documentation Raw data will be read from /scuba/m99b/20000127/ Reduced data will appear in /users/timj/oracdr/docs/sun231 +++++++++ For online SCUBA reduction use oracdr -loop flag +++++++++ For comments specific to SCUBA data reduction mail email@example.com For problems with the ORAC-DR system mail firstname.lastname@example.org http://www.jach.hawaii.edu/UKIRT/software/oracdr/
A warning is printed if the input directory can not be found on the system.
Once this is done, the next step is to set the location of the output directory. By default, the directory from which the oracdr_scuba command was issued is chosen. In order to override this value, the ORAC_DATA_OUT environment variable must be set:
% setenv ORAC_DATA_OUT /largedisk/myoracata/
All ORAC-DR output files will appear in ORAC_DATA_OUT.
