| Abstract: |
The pipeline calibration program (calcos) for the Cosmic Origins Spectrograph
(COS) was originally written based on requirements established in 2002.
While the basic outline remains the same, much has been learned about the
instrument since then, and extensive testing of calcos has helped reveal
shortcomings (aka bugs).
This paper describes some of the more significant changes, such as for
wavelength calibration, keywords for the world coordinate system, and
improving the data quality flags. |
