Xdescrip.mms is for VMS; Observe.MSC is for Microsoft C on the IBMPC;
XAstring.h is for use on the Atari ST where it should be named
X'strings.h', since this header is apparently not provided with MWC.
X
X2)
XYou may need to change things in main.c, especially the time functions
Xand default location.
X
X3)
XThe following awk scripts may be useful. They are for use in editing
Xthe .sif files produced when "observe" is used for a range of dates.
XUse dataconv to produce a 'lineread' or 'binfull' file from the
Xresulting editted .sif file.
X
XIf you don't have and can't get awk, you can edit the program to
Xproduce the output you usually want.
X
Xvelim removes the labels from vector commands,
Xe.g.
Xawk -f velim.awk jan.sif > jan.sif2
Xdataconv -i jan.sif2 sif -o jan.binfull binfull
X
XTo eliminate all the symbols from the file, use
Xawk '($4 ~ /V./) {print $0}' FS=";" OFS=";" jan.sif > jan.sif2
Xdataconv -i jan.sif2 sif -o jan.binfull binfull
X
Xrange.awk removes all but the first and last labels for each planet,
Xand all but every Nth symbol. M must equal the number of days in the
Xrange of dates.
Xe.g.
Xawk -f range.awk N=7 M=31 jan.sif > jan.sif2
Xdataconv -i jan.sif2 sif -o jan.binfull binfull
X
X
Xaltaz.awk selects fields from the .altaz file. Fields are printed in
Xthe order azi alt, for obect NAME at time TIME, where TIME is
X"sunset", "evetwil", morntwil", or "sunrise".
Xe.g.
Xawk -f altaz.awk TIME="evetwil" NAME="Austin" aus.altaz > aus.data
X
Xtimetable.awk selects fields from an .eph file for object NAME. The
Xfields may be specified as TIME ("rise", "trans", "set" ) or FIELD
Xnumber, e.g.
X
Xawk -f timetable.awk NAME="Austin" TIME="set" aus.eph > aus.set_times
Xawk -f timetable.awk NAME="Austin" FIELD=9 aus.eph > aus.mag
