NACO pipeline (called conicap) supports the reduction of all science frames taken in imaging mode. There is a restriction concerning the minimum number of raw frames in the stack depending on the choosen sky estimation method. As well as for the ISAAC pipeline (called isaacp) frames taken with the GenericOffset template will only sucessfully reduced, when the cumulative offsets do not leave a central square of the image to be specified in the ini file. The instrumental modes SPECTROSCOPY, CORONOGRAPHY and POLARIMETRY are not supported in P70.

Recipes and products

The following NACO sceince products are created from raw science files (click here for a complete overview of science files and recipes):

raw frame(s) product recipe description product(s) NC_IOAJ naco_img_jitter   reduce image stack <prod>.fits, <prod>.log, <prod>.paf

Science frames of instrument modes SPECTROSCOPY, CORONOGRAPHY and POLARIMTERY are not supported by the pipeline.

Association rules

For the reduction of science data calibration products are required. The selection of appropriate calibration products follow the association rules.

Naming scheme

After production and certification, the science products are renamed after a scheme which includes type, creation data and relevant NACO setting.

NACO science frames require a cascading scheme where the mutual dependencies of products and raw frames have to be respected. Some products (startrace tables, arc tables) can be produced from raw files only, but most products require the prior generation of other calibration products. The proper sequence of all these production steps is called the calibration cascade.

Within that cascade, all products are checked with respect to their quality and their relationship in time. This means e.g. that a master flat is not only generated using an arbitrary quality-checked frame, but that specific frame is chosen which at the moment of processing is closest in time.

All products created by QC Garching follow the science reduction cascade.
