Matched version number in schemaLocation attribute to updated value in Version tag. ZCB 2025-12-04T13:28:04Z Added MetadataRightsList. Updated to 2.7.1. ZCB For each Carrington rotation, there are two coronal synoptic maps of the sun in each of 3 Fe lines (171A, 195A, 284A) and in He (304A) These maps are from the Extreme Ultraviolet Imaging Telescope (EIT) on the SOHO spacecraft. The two maps for a given day and wavelength differ in that one has latitude on the Y axis and the other has sin(lat). There is also a FITS file for each day and wavelength. As of 01/11/2012, the maps spanned Carrington rotations 1911 (start day June 28, 1996) through 2055 (end date April 26, 2006) Please acknowledge the SOHO/EIT science team.
