Single-site synoptic maps

In addition to network merged synoptic maps, NISP Data center now creates single-site synoptic maps. These maps are used to monitor the magnetogram data products as derived using newly deployed EVT cameras and to evaluate the impact of merging data taken with two different type of cameras into a network-merged data products. Two images provide the examples of single-site (GONG/LE, top) and network-merged (bottom) synoptic maps for Carrington rotation (CR) 2296 recently created by Thomas Wentzel. Two maps are nearly identical, which indicates a  good level of uniformity of observations taken at different sites.
