Rerunning the Pipeline

The repipelining task for OM data taken in fast mode is omfchain. It produces images of the detected sources, extracts events related to the sources and the background, and extracts the corresponding light curves. At present, unlike omichain, omfchain does not allow for keywords to specify filters or exposures; calling this task will process all fast mode data.

To run the pipeline on fast mode data with the GUI:

1)

In the Available Tools panel, under ``XMM-SAS'', call omfchain.

2)

In the task pop-up window, click ``Run''.

To run the pipeline on fast mode data in the Command Window, type:

omfchain

There are two types of output files: those that start with f are intermediate images or time series files; those that start with p are products. The output files are are described in Table 9.2.

To demonstrate some of these output files, we have rerun the pipeline on the example dataset and downloaded the output to a local machine. The processed image in sky-coordinates from one exposure, P0411081601OMS006SIMAGE1000.FIT, is shown in Fig. 9.2 (left). The background-subtracted light curve produced automatically by the task, F0411081601OMS006TIMESR1000.PS, is shown in Fig. 9.2 (right).
