Python scripts and jupyter notebooks to analyse the SO/PHI-HRT data from the Active Region Long Term campaign in October 2023

Campaign Details

Oct 12 - Oct 20 : the campaign dates.

Co-coordinators: Jonas Sinjan and Laura Hayes.

Oct 12 - Oct 17 11:00

• Tracked one new active region that emerged a few days prior on the backside of the Sun.
• SO/PHI-HRT started tracking just past quadrature, with the AR at disc centre for SO/PHI-HRT, and very close to the limb in SDO/HMI.
• At Oct 17 11:00 this active region was a disc centre for SDO/HMI.

Oct 17 11:00 - 21:00

• Campaign interuppted for a polar campaign co-ordinated with Hinode.

Oct 17 21:00 - Oct 20 00:00

• Tracked a different active region that again emerged a few days prior.
• Unfortuneately the pores that emerged did not develop into strong sunspot(s).

Codes/Pipelines developed for analysis phihrt2sdohmi

src/hrt_wcs_corr_pipeline.py -> Pipeline to correct the WCS keywords in HRT

• reproject HMI Ic onto HRT detector frame
• cross-correlate with HRT icnt and find X-Y translation
• output the CRPIX and CRVAL errors to json files

src/reproject_pipeline.py -> Pipeline to reproject HRT data onto HMI detector frame

• reproject HRT blos or icnt onto HMI detector frame
• uses WCS errors calculated prior
• outputs remapped HRT and target HMI maps as sunpy map objects to pickles

src/reproject_mu_pipeline.py -> Pipeline to reproject HRT $\mu$ maps onto HMI detector frame

• identical to reproject_pipeline.py but instead computes the $\mu$ value in each HRT pixel
• reprojects these $\mu$ values onto HMI detector frame
• computes the $\mu$ values in the HMI detector frame
• outputs these $\mu$ maps as sunpy map objects to pickles

src/load_hrt_hmi_files.py -> Pipeline to load and select all the desired HRT and HMI files

• input start and end time
• finds HRT and HMI file pairs
• used as input object for other pipelines

src/download_all_hmi_files.py -> Download HMI files that correspond to HRT files from JSOC using drms

• Find light-travel corrected time on EARTH for each input HRT file
• Downloads the desired HMI file such that each HRT file has corresponding HMI file

Misc files

src/stereo_help -> helper functions for cross-correlation

src/reproject_funcs.py -> heavy lift functions for reprojection and $\mu$ computation
