COMMAND TYPE : UTILITY
A DIRA catalogue can be written in FITS format on tape or on disk; this is useful when the user wants to transport catalogues between two computer centers or he wants to insert data table in other astronomical packages, like MIDAS, that uses FITS as input formats. This command can be used to transport catalogues between two DIRA2 database; all the DIRA descriptors are saved in standard (and nonstandard) keyword. Moreover, the documentation file is written in a second table (XTENSION='DOCUMENT') in the FITS file. The coordinate fields are written using the DIRA standard formats.
The command DB_FROMFT can read these FITS files and insert catalogues in the data base without any more instruction. So the use of the commands DB_TOFITS : and DB_FROMFT is the best way to interchange catalogues (fully documented) between computer centers.

DIRACAT1, DIRACAT2, DIRACAT3, DIRACAT4, DIRACAT5
DIRADOC1, DIRADOC2, DIRADOC3, DIRADOC4, DIRADOC5
that contain the records of the master files DIRACAT.DB and DIRADOC.DB relative to the catalogue.
These keywords are read by the DB_FROMFT to have the complete description of the catalogue.
