Reference File Information by Instrument
You can find here the specifics of each instrument's reference files as described on the SI websites. Please note that ftp-based shortcuts are provided to allow quick access in most cases to the reference files, which are stored on-line for convenience. However, the most reliable method for obtaining reference files is via the archive.
If you need to request individual or multiple files from the MAST archive web site use the first nine characters of the file name followed by an asterisk, or the entire unique name given on the SI web pages linked to below. In order to retrieve reference files from MAST, you must overide the retrieval options. That is, once in the "Retrieval Options" window, you must override the defaults by entering the extension(s) of the file(s) requested. For example, if you are retrieving a bias reference file (with extension bia), enter "bia" in the box "or enter a specific extension:" and then submit your request.
To retrieve any one of these files using StarView please follow
these instructions.
