HMI Vector Magnetic Field Data - Versions and Referencing

HMI Vector Field data are available at hmi.B_720s

HMI Data 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 B_VERSION

• 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

This first release version was processed in a specialized way that was developed for individual active regions and tested for AR 11158 in February, 2011. Level 1.0 data were first released in October, 2011. Data released with this version number are described in VectorPaper. As the processing modules are improved, the data level will be incremented and documentation will be provided

HMI B Version 2.0

First Version of Full Disk Pipeline Data

• - Not yet released
