Versions of Reduction Code

HMI Data Reduction Modules are characterized by a version number. The version number indicates how the data have been processed. The principal version keyword for HMI.B_720 is BCODEV

Currently:

  • Modules automatically provide a keyword that gives the CVS version details:
    • CODEVER0 tells the version of the IQUV module
    • CODEVER1 tells the version of the gap filling module
    • CODEVER2 tells the version of the temporal interpolation module
    • CODEVER3 tells the version of the polarization calibration module
    • CODEVER4 tells the version of the VFISV module
    • CODEVER5 tells the version of the disambiguation module
    • INVCODEV is a programmer-provided indication of the last time the VFISV module was edited

HMI B Version 1.0
