Investigate missing pointings files on day of TCM (04/07/2026)

Algorithm Description:

Investigate data flow for ENAs + GLOWS on day of TCM (2026/04/07)

On 04/07 a TCM was performed with multiple repoints in that day. Noticed that Hi has multiple L0 files from multiple pointings, but not multiple L1C files. Need to trace this through to see where processing dropped.

Notes from the Nav/ACS team:

The first one you have highlighted at 10:00z, is the normal daily repointing maneuver. The other two are the two precession maneuvers (one in plane, one out of plane) executed as part of TCM-8. The number of precession maneuvers varies based on the TCM/SKM design.

Thanks,

Investigating Hi data has led to the following:

• The L0 file for pointing 210 contains only HK data. Hi did not go into HVSCI during pointing 210.
• L1A versioning is wrong. The batch starter appears to have only looked at the date when determining versioning. As a result, pointing 209, 210, and 211 are versioned as v001, v002, and v003 respectively.
• L1B files appear to all have been produced with the exception of goodtimes. Goodtimes was only generated for repoint 211:

• It is unclear why goodtimes for repoint 209 did not get kicked off.

Investigating Ultra data:

• Ultra L0 files exist only for pointing 211.
• Based on WebPODA query, there should be data for pointing 209, but nothing was found for pointing 210.

Investigating Lo data:

• Lo L0 files exist only for pointing 211
• Based on WebPODA query, there should be data for pointing 209, but nothing was found for pointing 210.

Investigating GLOWS data:

• GLOWS L0 files exist only for pointing 211
• Based on WebPODA query, there should be data for pointing 209, but nothing was found for pointing 210.
