Optics runs with HMS@-5.587 GeV/c, SHMS@-8.55GeV/c in Aug 2022. See summary at https://logbooks.jlab.org/entry/4025938

• new SHMS matrix:
  • according to Holly, a bug was found in this new matrix, she needs a few days to fix it. --Mar 15, 2023
  • theta, phi, y: https://hallcweb.jlab.org/doc-private/ShowDocument?docid=1198
  • delta: https://hallcweb.jlab.org/doc-private/ShowDocument?docid=1205

• • Aug 11: newer version with the raster sign flip issue fixed https://hallcweb.jlab.org/elogs/X%3E1+%26+EMC/249
  • Aug 14: latest version https://hallcweb.jlab.org/doc-private/ShowDocument?docid=1205

HMS

HMS optics data from pionLT: https://hallcweb.jlab.org/wiki/index.php/12_GeV_HMS_Optics_Data

Standard matrix

The standard matrix for p0<5GeV/c. Should work up to 5.8GeV/c since we are modify the dipole central setting to give the correct ytar versus yptar. Need to cross check with other optics data b/w 5-5.8GeV/c (per Mark Jones).

• file from 2018: File:Hms recon coeff opt2018.txt
  • already in hallc_replay_XEM/PARAM/HMS/GEN/hcana_fa22.param, no further change needed
• to do: check with hydrogen elastic data?

6.3 GeV/c saturated

Part of PionLT optics data. May not be analyzed.

6.6 GeV/c saturated

waiting for Jacob Murphy's reply.
