Detailed description of the data product¶
Data product definition referencing a FITS file containing a saturated star PSF. It is used to (very) roughly identify star pixels in the flagmap of a VIS exposure. It is just used as an indication of where stars signal is located.
It is a broadband ‘fat’ PSF used to flag star shapes during ghost flagging processing to try to separate star signal from ghost signal.
