Task

Commands to Reduce Last Night's Data

1. Catalog FAST raw data archive

Unless otherwise noted, commands can be run from any directory.
Create a local log file for one night in the raw directory, and display the PDF file, camblog.pdf to the screen. If no date is given, last night's data is assumed. If the log file exists, it is not re-created. The PDF file of the log is displayed, if possible.

Each observation is in a separate 2-dimensional FITS file with a reduced file number (RFN=[nnnn]) assigned from 0001 for each night. Postscript (camblog.ps) and PDF (camblog.pdf logs are created from the FITS headers. Entries are added to the FAST raw database and FAST raw object file database, which can be searched using the -r option of fastsearch.

1. Catalog FAST raw data archive

2. Transfer raw data to reduction/working directory

3. Align spectra for one configuration
