SELFCAL returns results in several variables, creates a CGAINS array
containing the Gain values, and one file to display the computed correc-
tion. The file name is specified by SELF_SNAME.
The result variables are:
SELF_APPLIED
Indicates whether the solution has been applied
SELF_STATUS
Indicates if a solution has been computed
SELF_DYNAMIC[Self_Loop+1]
The dynamic range at each iteration
SELF_RMSCLEAN[Self_Loop+1]
The rms noise at each iteration
