With two additional parameters, applysel can also edit the quicksat.mag file in case it is too large to run 'all sats'. (Perhaps this problem has been fixed in quicksat) -- bjorn@tt-tech.se (office) b_gimle@algonet.se (home) -- -- http://www.algonet.se/~b_gimle -- -- COSPAR 5918, HAMMARBY, 59.298 N, 18.104 E, 55 m -- -- SeeSat-L / Visual Satellite Observer Home Page found at -- -- http://www.satellite.eu.org/satintro.html --
