Add mechanism for IPP to know that a given file has already been detrended (from header or filename)

[jester@…]

Sometimes (for processing of SDSS images, all the time), we want to inject images into IPP that are already flatfielded etc. I can make the PROCESSED reduction class the default in the camera.config, and/or I can update chipRun.reduction by hand after registering images in ippMonitor. But it would be useful for IPP to have a mechanism of recognizing automatically that a given image has already been detrended. This could be by specifying certain header fields, or in the SDSS case, the filename fpC*.fits tells you that the image is a reduced ("corrected", hence C) image produced by the frames pipeline (hence fp).

a general mechanism might allow a reduction class to be tied to a header keyword rule. alternatively, each analysis step could / should always set a certain header keyword to show it has been performed, and the rules defined to inhibit that analysis if that keyword exists.

(um... not doxygen).

(sorry; last comment went to the wrong bug)

[jhoblitt]

has this been dealt with?

No, and I don't think it's in the long range plan.
