I'm adding another feature to Element Manager and have a question for the 2line experts out there. I've been asked to add sorting capabilities on the radar cross section of satellites. This information is available at OIG in the "Satellite Situation Report". I need to import the radar cross sections of satellites into two line elements. My thinking is that I will place that data in the 40th column of line0 right after the visual magnitude info provided by Molczan/McCants. So: ALOUETTE 1 0.9 1.1 0.0 8.2 d xxxx.xxxx 1 00424U 62B-A 1 90 25.21309753 .00000220 00000-0 25410-3 0 2561 2 00424 80.4628 67.0294 0022286 281.5113 78.3546 13.67284761363155 the x's on line0 would hold this value. Comments? Thanks -- Rick email@example.com PS. The next update will sort the visual magnitude number too.
