FORTRAN Routines

Packaged access to SuperCOSMOS mapping mode data from FORTRAN is provided by the COSMAP routines. These provide a FORTRAN-callable interface to the bigio library which actually accesses mapping data. Both bigio and COSMAP are written in C, and the Starlink CNF/F77 utilities are also required to enable a FORTRAN program to be linked successfully.

You can

get COSMAP from ROE by ftp

get bigio from ROE by ftp

get CNF from Starlink by ftp

When you have unpacked the tar files you need to compile them all using cc.

eg.

cc -c -o bigio.o bigio.c

Note that COSMAP needs to include header files from both CNF and bigio.

Standalone applications written in FORTRAN can then be compiled and linked using a command such as

f77 -o writemap writemap.f cosmap.o bigio.o cnf.o

• COSMAP_CLOSE - close a bigimage
• COSMAP_CREATE - create a bigimage
• COSMAP_ERRTRAN - translate an error number
• COSMAP_GETLHEIGHT - get the lane height of a big image
• COSMAP_GETLWIDTH - get the lane width of a big image
• COSMAP_GETMAP - return a rectangular area of a big image
• COSMAP_GETNLANES - return the number of lanes in a big image
• COSMAP_GETROW - return a row of pixels from a lane
• COSMAP_GETTYPE - return the data type of a big image
• COSMAP_OPEN - open a big image
• COSMAP_PUTMAP - put a rectangular area into a big image
• COSMAP_PUTROW - put a row of pixels into a lane
