NAME

       swetest - swetest.c

SYNOPSIS

       swetest Swiss Ephemeris test program.

DESCRIPTION

       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.

       The Swiss Ephemeris did not arise in the UNIX/Gnu Linux world  and  hence  the  people  at
       Astrodienst  did  not  create UNIX/Gnu Linux style manpage for swetest. Please consult the
       following files:

                 -hcmd  display commands

                 -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
          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.

                 -house[long,lat,hsys]
                        include house  cusps.  The  longitude,  latitude  (degrees  with  DECIMAL
                        fraction)  and house system letter can be given, with commas separated, +
                        for east and north. If none are given, Greenwich UK and Placidus is used:
                        0.00,51.50,p.  The output lists 12 house cusps, Asc, MC, ARMC and Vertex.
                        Houses can only be computed if option -ut is given.
                 -hsy[hsys]
                        house system to be used (for house positions of planets) for  long,  lat,
                        hsys, see -house

                 -geopos[long,lat,elev]
                        Geographic  position. Can be used for azimuth and altitude or topocentric
                        or house  cups  calculations.   The  longitude,  latitude  (degrees  with
                        DECIMAL  fraction)  and  elevation  (meters)  can  be  given, with commas

       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.

                      <RETURN>        repeat the last entry

                      .               stop the program

                      +20             advance the date by 20 days

                      -10             go back in time 10 days

             consecutive steps (-n100) with 5‐day steps (-s5) with
             longitude in degree‐sign format (-f..Z) rounded to minutes (-roundmin)
