This includes sources which are clearly known to be a point source but the overlap of SSL and SSW still presents a discontinuity. It can be corrected using the PointingOffsetCorrectorTool available in HIPE v.14.

  Header parameters:
  • Ratio SLW First Ring before background subtraction [%]: This parameter refers to the ratio of the flux of the first ring of SLW off-axis detectors to the flux of the central detector.
    This was obtained by calculating the ratios of the flux of every SLW off-axis detector to the flux of the central detector for each value of frequency. In order to eliminate the dependancy on frequency, the median was taken for each SLW off-axis detector ratio array, resulting in a single value for every one of them. The final value resulted from taking the median from these last values.
    The off-axis detectors used are SLWB2, SLWB3, SLWC2, SLWC4, SLWD2 and SLWD3.
