Swiss Ephemeris
Test Output


  


  Swetest computes a complete set of geocentric planetary positions,
  for a given date or a sequence of dates.
  Input can either be a date or an absolute julian day number.
  0:00 (midnight).
  With the proper options, swetest can be used to output a printed
  ephemeris and transfer the data into other programs like spreadsheets
  for graphical display.

  Command line options:
     help commands:
        -?, -h  display whole info
        -hcmd   display commands
        -hplan  display planet numbers
        -hform  display format characters
        -hdate  display input date format
        -hexamp  display examples
     input time formats:
        -bDATE  begin date; e.g. -b1.1.1992 if
                Note: the date format is day month year (European style).
        -bj...  begin date as an absolute Julian day number; e.g. -bj2415020.5
        -j...   same as -bj
        -tHH.MMSS  input time (ephemeris time)
        -ut     input date is universal time
	-utHH:MM:SS input time
	-utHH.MMSS input time
     output time for eclipses, occultations, risings/settings is UT by default
        -lmt    output date/time is LMT (with -geopos)
        -lat    output date/time is LAT (with -geopos)
     object, number of steps, step with
        -pSEQ   planet sequence to be computed.
                See the letter coding below.
        -dX     differential ephemeris: print differential ephemeris between
                body X and each body in list given by -p
                example: -p2 -d0 -fJl -n366 -b1.1.1992 prints the longitude
                distance between SUN (planet 0) and MERCURY (planet 2)
                for a full year starting at 1 Jan 1992.
	-DX	midpoint ephemeris, works the same way as the differential
		mode -d described above, but outputs the midpoint position.
        -nN     output data for N consecutive days; if no -n option
                is given, the default is 1. If the option -n without a
                number is given, the default is 20.
        -sN     timestep N days, default 1. This option is only meaningful
                when combined with option -n.
     output format:
        -fSEQ   use SEQ as format sequence for the output columns;
                default is PLBRS.
        -head   don't print the header before the planet data. This option
                is useful when you want to paste the output into a
                spreadsheet for displaying graphical ephemeris.
        +head   header before every step (with -s..) 
        -gPPP   use PPP as gap between output columns; default is a single
                blank.  -g followed by white space sets the
                gap to the TAB character; which is useful for data entry
                into spreadsheets.

  Date entry:
  In the interactive mode, when you are asked for a start date,
  you can enter data in one of the following formats:

        1.2.1991        three integers separated by a nondigit character for
                        day month year. Dates are interpreted as Gregorian
                        after 4.10.1582 and as Julian Calendar before.
                        Time is always set to midnight.
                        If the three letters jul are appended to the date,
                        the Julian calendar is used even after 1582.
                        If the four letters greg are appended to the date,
                        the Gregorian calendar is used even before 1582.

        j2400123.67     the letter j followed by a real number, for
                        the absolute Julian daynumber of the start date.
                        Fraction .5 indicates midnight, fraction .0
                        indicates noon, other times of the day can be
                        chosen accordingly.

                repeat the last entry
        
        .               stop the program

        +20             advance the date by 20 days

        -10             go back in time 10 days
