The target book images will generally come from the digitized sky survey plate material available from the STScI (i.e. the same plates used to generate the HST Guide Star Catalog). We have developed a program to properly align and scale these images to a standard size field and produce a `postscript' output of the image with the appropriate bells and whistles for the target book. For a few targets (e.g. nearby galaxies, bright nebulae, H II regions, etc.) the digital data will not be of use and special plate material will need to be located and incorporated separately. An image scanner is available is a suitable image can be located for such special targets.

HUT scientists support the production of the target book in two significant ways. Selection of HUT guide stars in the SDFs is actually supporting the target book as well as the sequence loads, since our target book program reads the information on the selected guide stars and marks both the object position and the guide stars on the digital image for each target book page. The other support activity involves producing a HUTSIM2 output file of the simulated counts spectrum for each object (see above), with an accompanying short text file of descriptive material that may be of use to the Payload Specialist or ground personnel who are setting up an observation. A "template" file is provided for the text inputs. A program run by HUT personnel converts these ascii inputs (including information from the WUPPE team as well) into the `postscript' output files. The postscript files are then printed on a high quality 600 dpi laser printer to produce the hard copy used in the target book.
