Download FITS filament maps as tar archive

» All Filament Data of 20250528 ...
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.
