Next Steps

Automatic Weighted Batch Pre-processing for Comets 


Update 2024-10-24: To some unknown reason this information is missing since a while after performing automatic batch pre-processing.

Update 2025-10-24: Astrometric data are no longer missing, reason was probably a missing check on the Astrometric Checkbox in the FBPP and WBPP Pre-Processing Batch tool. 

Later steps will require Astrometric data (OBJCTRA and OBJCTDEC) to be included in the FIT, FITS or XFIT header of the integrated file. 


How to update the OBJCTRA and OBJCTDEC coordinates

In order to reintegrate the astrometric data into the files, a plate solving (Image or Plate solver) should be carried out. Depending on the brightness of the image background, a background improvement may have to be carried out first so that the image solver does not fail.
