The BOXCAR and GEX programs can all produce output files in FITS format.
(Note that the FITS file is optional in BOXCAR, and that BOXCAR can also
write a MELO file in RDAF format readable by IUESPEC.) Due to
the constraints on file name length imposed by DOS, the following convention
has been adopted:
FILENAME
This will be an eight-character string consisting of the
camera mnemonic (e.g., SWP) and the image sequence number. For NEWSIPS
data the filename will be the same as that for the original SILO file.
EXTENSION
This will be a three character code consisting of:
- A letter designating the type of data the file contains. For BOXCAR
output this will be ``B''; for GEX output this will be ``G''.
- A number designating the aperture from which the data were extracted:
0 Unknown aperture.
1 Large aperture.
2 Small aperture.
3 Both apertures.
- A letter designating file format: F for ``FITS'' format.
These files can be read with IFITSRD. For example, suppose we
have done small aperture extractions of SWP12345:
BOXCAR extraction:
ifitsrd,'swp12345.b2f',1,h,eh,w,f,q,g,b,n
GEX extraction:
ifitsrd,'swp12345.g2f',1,h,eh,w,f,err,q
