    Create the Sic structures mapping the Mrtcal internal buffers, namely:
      - IMBF%PRIM, IMBF%SCAN, IMBF%FRONT, IMBF%BACK 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.

    Note that these variables are not updated when the buffers are  changed.
    For safety they should be updated by recalling the command.
