The images have been recentered (less than 1 pixel precision), information about coordinate system was added in the header, so that data can be further processed with existing solar libraries and softwares. The image file format is FITS. The FITS header has been made homogeneous throughout the dataset and complies with the SOLARNET recommendations.
