| QC1PARAM |
QC1 parameters written into QC1 table: QC1db names: skyline_position | skyline_rms | skyline_offset | skyline_number | avg_accuracy QC1 params created by pipeline: avg_accuracy (from wavelength calibration data) QC1 params created by this procedure: all others | ||||||||||||||||||||||
| 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 | ||||||||||||||||||||||
