K-Cor White Light Level 1 normalized radially graded filter (NRGF) Data

Level 1 (nrgf) data: FITS and GIF Level 1 images with a normalized radially graded filter (nrgf, Morgan et al. 2009, adapted by Silvano Fineschi and Sarah Gibson for KCor use) to maximize image contrast. These data are ideal for measuring positions of coronal structures such as CMEs and helmet streamers.

The cadence of these specially processed images is 2 minutes. If you require 15 second cadence, please contact us.
