Open rfshipman opened 2 weeks ago

rfshipman commented 2 weeks ago

In the FITS files of version of 0.9 pipeline.

NAXIS1 for Band 1 = 4703 not 512 NAXIS1 for Band 2 = 9311 not 1024

The units of axis 1 are m/s. Per channel this is 9.18 m/s /channel and 9.09 m/s per channel

Level 0.8 fits identifies the frequency scale also for Axis 1 in MHz Band 1 in level 0.8 notes 9.7847 MHz / channel

Are the units consistent in L09?

@rfshipman: NAXIS1 in the FITS files is determined by the data table and not by the spectra. You should look at the appropriate TFORMx keywords to get the length of the spectra and associated data like channel_flags, etc. Also, the units in L09 data will change with the data format change coming up.
