VISIR science files and recipes

This page describes processing techniques of the VISIR science data.

More information is given in the following sites:

 

VISIR SCIENCE data have been processed with the up-to-date version of the pipeline. Please note that ESO is not assuming any responsibility in respect to the usefulness of the reduced data. The adopted reduction strategy may not be suitable for the scientific purpose of the observations.

 

IMG_OBS

Purpose. The recipe processes the stack of raw science frames, estimates and subtracts background, recovers the final image.

Input

TPL.ID VISIR_img_obs_AutoChopNod
DPR.TYPE OBJECT
TAGIM_OBS_CHO_NOD_JIT,
IM_OBS_CHO_JIT,
IM_OBS_NOD_JIT,
IM_OBS_DIR_JIT
groupingINS.PFOV, INS.FILT1.NAME

IMG_OBS_CONTRIB_MAPcombined image contribution map

QC parameters

QC.BACKGD.MEAN mean of the estimated background

 

SPEC_OBS

Purpose. The recipe processes the stack of raw science frames, estimates and subtracts background, identifies sky lines, recovers the final spectrum.

Input
