Constraints: we have already agreed on a filenaming system for the raw data with Alan Pickup. UKIRT has a policy of resetting the run number each night back to 1..... At telescope files will be called wayyyymmdd_12345.sdf, wbyyyymmdd_12345.sdf ...... where the a,b,c,d correspond to detector, w stands for wfcam and the 5 digit run number is just that We will create 2D raw MEF files with names like w_yyyymmdd_12345.fit We are proposing a simple prescription for stacked, superduper frames or whatever.... The run number comes from the first run in the sequence and has a unique few letter code appended to denote if its a stack, interleave ........ so standard superframe w_yyyymmdd_12345_sf.fit stacked dither w_yyyymmdd_12345_st.fit stacked superframes w_yyyymmdd_12345_sf_st.fit tile from superframes w_yyyymmdd_12345_sf_tl.fit and so on....... These are all MEFs so we drop the a,b,c,d. If its been processed dark correction and flatfielding are implicit and the processed and raw data are stored on different systems. This way we have a simple trace back to the original filenames at the telescope. Catalogues generated from frames will be rootname_cat.fits and confidence maps for frames rootname_conf.fit. For generic confidence maps ie. one for each passband for each night for non-stacked data we could just use soft links rather than duplicate data or not bother since info regarding correct confidence map is in the header.
