FLAMES image headers ----------------------- This is an "incomplete" list of tips with the goal of helping the users to extract the more relevant information from the FLAMES image headers. 1. In order to know the correspondence between observed target, allocated fibre, and extracted spectrum, please follow the following steps: from the OzPoz binary table one gets the correspondence between observed target and button (column #9, identified as BN) from the FLAMES binary table one can associate the button (column #8, identified as RP) to the extracted spectrum (column #2, identified as FPS) 2. Please use information provided in the DataSummary files in order to have the complete correspondence between raw and reduced frame. In the preliminary version of the GIRAFFE pipeline used during the Dry Runs, the name of the RAW frame is not logged in the header of the final reduced image (but only the FLAT image used for the flat-fielding). This will be fixed in the forthcoming versions of the Geneva Data Reduction Software. In the preliminary version of the UVES-fibre pipeline the binary tables in the reduced frame are empty. Already fixed in the most recent version, still under final testing. 3. Note that in the OzPoz table, columns "err_error", "theta_error", and "in_tol" (which contain respectively the fibre position errors and information about the 40micron accuracy - if achieved or not) are currently computed in excess of the true value. Consequently the flag "in_tol" is often set to F (out of tolerance) although the fibres are placed within tolerance. 4. Naming convention for UVES-fibre reduced spectra : Example: r.UVES.*0002-0038.fits each number corresponds to one EEV spectrum r.UVES.*0045-0081.fits each number corresponds to one MIT spectrum Number of spectra depends on adopted fibre-configuration. 5. GIRAFFE Wavelength Calibration (14.3.03): because of an inappropriate model assumed for the input slit geometry, shifts up to 10km/s fibre to fibre have been detected. These can be easily calibrated using sky-lines in those regions that have some. The new revised pipeline should become available shortly, in order to re-process the data for a thorough scientific analysis. We will do our best to update this list as problems and solutions are found. Thanks in advance for your understanding!
