Whether subsampling is to be used when doing X-polynomial fits.
Set to TRUE if subsampling is to be done.
This parameter is only used when polynomial fitting in the X-direction is enabled (TUNE_FFNXPLY > 1) and causes the program to subsample (10 samples per pixel) the spatial profile during fitting. This is useful when the balance factors `outside' the dekker, or at the very edge of the dekker (where the intensity changes quickly from pixel-to-pixel) are needed.
INTIIAL SUGGESTED VALUE: NO.
