How can I tell which pipeline processed my data? How can I tell if my data have been reprocessed under the most recent pipelines?

Check the header of one of your BCD files and look for the keyword 'CREATOR'. (e.g., imhead blah_bcd.fits | grep CREATOR). This is the software version that was used to process your data.

The pipeline history file for your instrument can be found in Appendix A of the Instrument Handbooks. If the value of your file's CREATOR is a number greater than or equal to the largest number on the pipeline history page, you've got the most recent version. If it does NOT match, you should re-download the data from the archive to get the latest version of the data.
