Download FITS filament maps as tar archive
» All Filament Data of 20210421 ... |
The tar archive contains filament maps for all processed Hα images
with at least quality=1. The maps contain the values 0 and 1, where 1 is the position of a detected filament. The header in the FITS files is mostly taken from the corresponding Hα file, so it should be compatible with standard solar software routines. |
