## SIC variables

Some SIC variables mapping the file header (of any kind) have changed:

- head%dim[:] is now a long integer array of dimension 7;
- head%where[1] and head%where[2], the “flat” positions of the maximum and minimum values have been removed , replaced respectively by head%minloc[:] and head%maxloc[:] array coordinates in the datacube.
- head%gene is now the length of only the dimension section.

New possibilities linked to the new UV data format are reflected in SIC. The command DEFINE UV checks more strictly the type of data. It defines the following additional SIC variables

        head%basemin    Minimum baseline
        head%basemax    Maximum baseline
        head%nvisi      Number of visibilities
        head%nchan      Number of channels
        head%nstokes    Number of Stokes parameter
        head%natom      Complex visibility size

In addition, for transposed UV tables, Head%U and Head%V SIC arrays are defined to point towards the U and V columns.
