Fix GLOWS L1B array sizing to use actual histogram length
Background
Per ISTP/CDF convention, all variables must be allocated to the maximum expected size (3600 bins), with unused values filled with
FILLVAL. In the GLOWS packet format,HISTOGRAM_DATAis a fixed 3600-element field. However,NBINSis a separate raw telemetry field propagated asnumber_of_bins_per_histogram— this encoded value (e.g. 225) is not the bin array length.If we get sent fewer bins, we still want the output variables to be of len 3600.
I found this issue when testing against validation data that is 255 bins long.
Fix
Replace
self.number_of_bins_per_histogramwithlen(self.histogram)wherever it sizes output arrays inglows_l1b_data.py. The field is retained in the dataclass output as a passthrough of the raw telemetry value.
