| ALGORITHM |
Description of algorithms: The whole rebinned frame is searched for emission lines. Then lines within +/- 1 pixel around skyline_position are selected and their offset with respect to the reference line is determined. The mean and rms of these offsets are stored in skyline_offset and skyline_rms. The number of skylines used is stored in skyline_number | |||||||||||||||||||||||||||
| CERTIF |
to be rejected only if obviously bad, e.g. curved or
slanted sky lines skyline offsets of more than 0.3 pixels violate the nominal calibration accuracy, but may be due to temperature differences between science and calibration data and are no cause for rejection | |||||||||||||||||||||||||||
