EIS Science Planning Guide• We are developing this on our web site:
http://www.mssl.ucl.ac.uk/solar-b/espg.html• Includes an EIS study form in order to ‘play’ with your own
personal observing plans.
• Includes a list of EIS studies produced by the EIS team• Includes line lists and intensities in different regions of activity• Includes a set of science data products• Includes a proposed operations planning procedure• Includes an initial science plan for the first 3 months
