Dear Sirs or Madams,

  Hello, I have a problem with FRING. I want to use one scan on a strong calibrator to do phase calibration to align all bands by removing a delay and phase from each IF. The timerang of FRING is 0 11 01 23  0 11 04 35 and the solint is 4. The timerang is less than 4 min, but there're 2 epochs for solution:

The output SN table of FRING is strange, row 11-19 is INDE:

****************************

     Half data would be "flagged by gain" while applying this SN table to the data. Could you tell me what's the meaning of INDE and what's the possible reason for generating such a SN table? Why half data is flagged while applying this SN table? Thanks in advance!
