ROSAT Status Report #43:
Dec 23, 1992
HRI Update
Updated information on the performance of the ROSAT HRI is now available via anonymous ftp on the rosserv.gsfc.nasa.gov machine.
The anonymous-ftp directory (pub/HRI_Info/HRI_report) contains the LaTeX (HRI.tex, together with "psfig.tex" and two "*.sty" style files which are referenced), DVI (HRI.dvi), and Postscript (HRI_nofigs.ps) files for the entire 27-page report, "The ROSAT High Resolution Imager (HRI)", dated November 1992. Also included are individual Postscript files for each of its 13 figures (cf. list below). The files HRI.dvi and HRI_nofigs.ps can be used with online "previewers" such as the Unix programs dvipage and ghostscript, respectively, while HRI.tex can be used (e.g., for keyword searches) with any text editor (albeit with the inconvenience of ubiquitous LaTeX commands). Hardcopies of the report (without figures) can be generated by printing "HRI_nofigs.ps" (e.g., in Unix, with the command "lpr HRI_nofigs.ps"); similarly, the individual-figure Postscript files can be printed to obtain hardcopies of the figures.
Please note that the figures have been kept separate (by substituting blank figures, "*ps_blank", in HRI.tex) from the Postscript file of the text because of problems with printing the entire report when the "encapsulated" figures were included. Figures 4, 5, 9, and 13 were found to hang some printers, apparently because color-level Postscript commands were included in these figures inadvertently during their generation. The use of a color printer for these figures may alleviate problems in obtaining hardcopies (if not, please request a hardcopy from the RSDC GOF). (There should be no problems with printing the other nine figures.)
