[MRTCAL\]VARIABLE [*|What [READ|WRITE]]
Create one or all the Sic structures mapping the Mrtcal internal buf-
fers, namely:
- IMBF%PRIM, IMBF%SCAN, IMBF%FRONT, IMBF%BACK, IMBF%DEROT map the FITS
HDUs for the scan,
- SUBS%BACKDATA, SUBS%ANTSLOW, SUBS%ANTFAST map the FITS HDUs for one
subscan,
- IMBDATA%TIME and IMBDATA%IMBF% describe a portion of data of the DA-
TA table,
- MHEAD%KEY, MHEAD%PRI, MHEAD%CAL map the sections of the index entry
which was read.
Default is *, i.e. the 4 structures will be created, but only one struc-
ture can be created with one of the keywords IMBF, SUBS, IMBDATA, MHEAD.
The structures can be created read-only (keyword READ) or read-write
(keyword WRITE) for further update with the commands MUPDATE/MWRITE. De-
fault is read-only.
Note that these variables are not updated when the buffers are changed.
For safety they should be updated by recalling the command.
