1. Airmass Calculation
... In most cases it will however be necessary to compute an appropriate airmass using the COMPUTE/AIRMASS . ... It is important to keep in mind that ``mean airmass'' and ``mean atmospheric extinction correction'' are different from the values at mid-exposure, especially for larger zenith distances. ... For reasonable combinations of exposure time and zenith distance, the weighted mean airmass supplied by COMPUTE/AIRMASS should be appropriate. ...
