Debug

This section has various debug plots from APERO products

Telluric map

../../../_images/debug_tcorr_map_plot_HD494_nirps_he_online_udem.png

Telluric map of e2dsff_tcorr_A files.Files are low-passed and corrected for the stars motion. The QC is displayed to the right of the image - in purple are the files that passed, in orange the files that failed.

Maximum Saturation level plot

../../../_images/debug_extsmax_plot_HD494_nirps_he_online_udem.png

Maximum saturation level measured at time of extraction

Measured effective readout noise before extraction

../../../_images/debug_effron_plot_HD494_nirps_he_online_udem.png

Measured effective readout noise before extraction

APERO Processing Debug Plot

../../../_images/debug_version_plot_HD494_nirps_he_online_udem.png

Plotting the version and processed date from the header from APERO. Note that offline reductions should lead to a straight line, while online reductions should be roughly a one-to-one with the Date axis.

APERO Calibration times plot

../../../_images/debug_mjd_cdt_plot_HD494_nirps_he_online_udem.png

Computed time between observation and calibration used. Some calibrations arereference calibrations (in purple) and thus diverge from the reference night, others should always be from the same night (orange) unless no calibration was taken that night in which case the closest calirbation in time should have been used.
