Smaller Pre Dec 21 flares could be duration shifted #358

Open grazwegian opened 1 year ago

grazwegian commented 1 year ago

In the time period where a duration shift is needed (before 09-Dec-2021) small to moderate flares were sometimes requested at full time resolution despite the lowest onboard time bins being larger than configured minimum time. As the data is at on-board time resolution these flares would be suitable for the duration shift to be applied. Currently the processing pipeline compares the lowest time bin in the data to the configured minimum time and therefore does not shift these events. One option could be to associate each flare with the requested minimum time and use that to determine suitability for duration shifting.

To add to this an example was found this week by Andrea of a larger flare where the time binning dropped to 0.5 but was determined by the pipeline as "possibly summed on board" and not shifted - solo_L1_stix-sci-xray-spec_20210908T170833-20210908T183205_V01_2109080238-65392.fits https://datacenter.stix.i4ds.net/view/list/bsd/id/4805

To update we have added in a keyword to the IDL GSW to manually request that the data is shifted during analysis (https://github.com/i4Ds/STIX-GSW/pull/180). This can be used for such cases so it is possibly not needed to make any changes to the data.
