GED
GED (Get Erne Data) is a set of IDL programs and auxiliary files for reading and manipulating ERNE level-2 and level-3 science data. In addition, ged is also the name of the main function of the system.
In principle there is only one ged program user needs to know: ged, an IDL function that acts as a front end for the other ged programs. The other functions are called automatically as needed based on the requested data type and prosessing parameter (IDL keyword) settings. However, an effective use of the system at its current state requires also some knowledge of what happens 'behind the scenes'. Specifically user should be aware what keywords are available to control the processing of the data in question. The available keywords depend on the 'lower level' functions that are used to read and process each data type.
