# MIRA / SIC variables

Most of the variables in the internal MIRA structure can be copied to and examine (e.g. plotted with GREG) as SIC variables. MIRA provides the following commands for defining and initialising these variables. For an explanation of the sections and their contents, I also refer to the document "Multi-Beam FITS Raw Data Format", revision 1.4. Variables derived from WCS ( = world coordinate system) FITS keywords have their leading number appended to the end of the keywords' names, for the sake for compatibility with FORTRAN (e.g. `CRVL4_1` instead of `1CRVL4`).
