... For an input list of EBOXDETECT source locations, simultaneous maximum likelihood PSF fits to the source count distribution are performed in all energy bands of each EPIC telescope. A description of the main properties of the detection algorithm may be found in Cruddace, Hasinger, Schmitt (1988). ... Note, that =1 in the case of the individual energy band detection likelihoods listed in source table rows with ID_BAND 0 and is equal to the total number of energy bands in the ID_BAND=0 summary rows. ...

... Instruments are more complicated than star catalogs, but a MIDAS table file is still useful for holding the description of an instrument. ... The main sub-table contains information about the passbands used, and the second sub-table describes the detector(s). ... Basic data for an instrument file include the passbands used (and any coding that is used to represent them in the data); the detectors used, and their properties; and general information about temperature control and optical cleanliness. ...

... The Observatory's heritage policy is to maintain and preserve the historic buildings, telescopes, telescope domes, scientific instruments and other material in its care, to place restored instruments and artefacts in their original locations in the building so far as possible, and to add to and maintain the integrity of the historic Library and Archives as a coherent, growing collection in the City of Armagh for future generations. ...
