This pull request updates the variable attribute configuration in imap_ialirt_l1_variable_attrs.yaml to standardize units and clarify descriptions for HIT instrument data. The main changes involve switching the UNITS field from "counts per second" to "counts" for several variables, and updating some CATDESC descriptions to better reflect the data and look direction.

Units standardization:

  • Changed UNITS from "counts per second" to "counts" for all electron, proton, and helium variables to accurately represent the data as total counts rather than rates. [1] [2] [3] [4] [5] [6]

Description clarifications:

  • Updated CATDESC for electron variables to clarify look direction and particle orientation (e.g., distinguishing between sunward and anti-sunward directions). [1] [2]
  • Revised CATDESC for proton and helium omni-directional variables to remove references to "sum of particles divided by full sky area" and clarify that the value represents counts. [1] [2]
