SCULIB_ANALYSE_PHOTOM_JIGGLE - analyse the jiggle map made by a bolometer during a PHOTOM observation

Description:

This routine analyses the jiggle map made by a bolometer during a PHOTOM observation. If status is good on entry the routine checks that the data array holds data for the specified bolometer. If it does not an error message will be output and the bad status returned. All being well the routine will analyse the data by the method specified in PHOTOM_ANALYSIS:-

AVERAGE - the `result' will be the mean of the jiggle points. The variance is the sum of the variances of the averaged data divided by the number of them squared. The result will be flat-fielded and reported to the user. If no valid data were available for the calculation of the mean then a warning message will be output but good status returned.

PARABOLA - the routine will call SCULIB_FIT_2D_PARABOLA to fit a 2-d parabola to the data and the `result' will be the peak of the fitted curve. If the fit is good the results will be flat-fielded and reported to the user. Otherwise the result quality is set bad but good status will be returned.
