Hi Martin: RE: I agree with Jim that a little more basic information is needed about what the angles are. I may be misinterpreting the discussion, but I had imagined that the angles as components of a spherical coordinate system centred on the satellite, with the nadir at (0,0) ... is that correct?
The projection_x_angular_coordinate and projection_y_angular coordinates are the angular distances from the satellite’s nadir in the E/W an N/S direction, respectively, from the ideal location of the imaging instrument in geostationary orbit. v/r randy > On Apr 20, 2018, at 4:06 AM, Martin Juckes - UKRI STFC > <[email protected]> wrote: > > I agree with Jim that a little more basic information is needed about what > the angles are.
