... Science Users Information > Science Publications > Science Announcements > Improvement to FLAMES Spectral Resolution and Sensitivity . ... The FLAMES GIRAFFE spectrograph is not kept at a controlled temperature, and thus, at the beginning of every observing block, GIRAFFE is re-focussed to take account of collimator temperature. ... The updated values lead to a substantial increase in spectral resolution and sensitivity across all settings, particularly for the high resolution ( HR ) settings. ...

... Specs . ... Data in folding and search modes will be output as FITS files. The DFB also has a mode that provides digitized baseband output suitable for the next generation of real-time coherent dedispersion systems. ... The output file will be a standard, pulsar folded profile with full polarisation and a given number of phase bins, frequency channels and subintegrations. ... The DFB is specified to allow 2048 frequency channels and 2048 phase bins for a 4-ms pulsar recorded with 8-bit sampling. ...

... OGIP spectrum for selected source region . OGIP spectrum for selected background region . ... The primary input to especget is an image data set and two spatial selection expressions which need to mark an extraction region around a point source and a source-free background region. ... All regions will be deleted from the image - new initial selections for source and background regions must be made In the first and second case especget is eventually invoked with the appropriate input. ...
