Electronic logs are recreated in Cambridge to include all the data taken on a night and to provide consistency in the UT Date. In IRAF, the package obslog is loaded. This package was created by Doug Mink using some of the e-log code from Mt. Hopkins. The obslog programs assume that the observer has created an e-log and the files .lis, .ps, .dvi (with a prefix which varies from observer to observer) exist.

  • lpar savelog to check the parameter oldroot.

    • If it isn't correct, i.e.,  doesn't match the prefix the observer has given (usually obslog or fastlog), set it by typing savelog.oldroot="whatever"

  • savelog

    • Savelog keeps the comment lines

  • lpar obslog

    • check to make certain the parameter logroot is what you want; I use camblog and set it by typing obslog.logroot=camblog

  • set page number by typing obslog.page=xxxx

  • addlog *.fits

    • Creates the new .lis file

  • initlog anygoodfile.fits

    • Pulls parameters from a data file to use in the e-log header

  • viewlog

    • Makes and displays the log (the .ps file)

    User can set different types of display such as xdvi (the default), ghostview, or acrobat.

  • printlog remake=no

    • Prints hardcopy of the night's log
