The latest release of the WISPR Data Users Guide is available here as a PDF document. It provides an overview of WISPR, the data products, the FITS header parameters, and contact information for the various Team Members. We also strongly encourage users to refer to the WISPR Calibration paper, Hess et al., 2021, available online via ADS and here (11M PDF) as a pre-print.
In the near future we plan to provide a SoloHI Python notebook tutorial. You can contact any of the SoloHI science team to request an advance copy of this, or to receive more instruction and information on the correct procedures for handling SoloHI data.
