User had various queries related to determining the pixel view vectors to allow atmospheric correction in ATCOR. The data he is interested in is GB06-10 (Chilbolton, 2006 day 168). Issues unsolved thus far:[[BR]] 1. Hassan reports the aircraft position seems to be off the position of corrected data by ~50m (possibly just that the sensor FOV is asymmetrical about the axis of flight, so it appears offset but actually isn't?)[[BR]] 2. Haven't been able to supply a formula for determining zenith and azimuth of the aircraft from a given ground pixel (zenith and azimuth of the aircraft from a point on the ground aren't hard, the problem is working out which point on the ground we should be working it out for at a given moment). Have also supplied a new test level 1 HDF for flight line 2 - he's been having problems with azgcorr hanging, suspect his level 1 HDF may be corrupt/otherwise incorrect, because it's substantially larger than the test one I got." support new alpha 4 high Support
