SWOT data missing for latitudes less than -56.5-degrees #198

I ran rads2grd4 for SWOT (cycles 301-315) and found that there were no measurements for bins less than -56.5-degrees latitude. I then compared rads/tracks/sw/b/c313/swp0567c313.nc to the same pass downloaded directly from EarthData, and while the EarthData file did contain measurements less than -56.5 the RADs file did not.

Here is an example of the command that I'm running: rads2grd4 --sat sw -V lat,lon,sla,time --min 2 --res 1 -C 313 -o grids4trend/sw_grids1_c313.nc

The offset for alt_gdrf and range_ku for SWOT in the Science orbit is too low (700km) to store the values when they exceed int4 and they are set to NaN. The field for sw/b will need to be changed and sw/b reprocessed.

Reprocessing of Cycles 314-317 (IGDR and OGDR) completed. Reprocessing of Cycles 301-313 (GDR) running. Should be finished later today (27 June).

Reprocessing of Cycles 301-313 (GDR) completed. All data has been synced to the RADS server.
