In the VLTI DataFlow the raw frames (FITS files) are classified
and associated to be processed by the data reduction pipeline and to be
distributed to the individual PIs. The associations are done using different
On Paranal: raw data are sent on the fly during the night on the pipeline
workstation, they are classified and associated with the DO
(Data organizer) and processed for quick-look purposes wihout requiring
further processing or calibrations.
In Garching: all frames including the day-time
calibrations and/or calibrations taken on different nights are available
when the science data of a night are processed. In this case, we can
associate scientific data to calibration data which have been taken
either before or after or even on a different night.
Each type of raw file needs to be classified in order to associate them
with the appropriate pipeline recipe (see association map ). The primary
FITS header keywords (DPR keywords and some of the TPL keywords) are cross
checked against a table. There are several steps in the associations (TBC). Several raw files can be associated to different calibration products .
The following tables shows the characteristics of the files associated
together to be processed with the pipeline recipe "reduce fringe"
