The Planets Version 2.02 |
The 1st line of this
file is the System II
Longitude of Jupiter's Great Red Spot (in degrees). Its a good idea
to check this value against other sources (eg Sky and Telescope magazine).
I will try to quote an updated value on the Castle Point Astronomy Club
website. Over recent years, the GRS longitude as drifted a few degrees
every year. One degree difference between the actual value and the value
in this file will give an error of 1.6 minutes in the calculations.
The 2nd line of this file is the new "configuration" line consisting of 10 characters. Each character controls a different feature.
| Character | Options | Default value |
| 1st char = STARTUP SCREEN | 0=skymap 1=Jupiter 2=Saturn 3=Solar System 4=Ecliptic Circle 5=LocationInput |
5 (Location Input) |
| 2nd char = SUMMERTIME | Y=yes N=no |
N (no) |
| 3rd char = FLIP N/S | Y=yes N=no |
N (no) |
| 4th char = FLIP E/W | Y=yes N=no |
N (no) |
| 5th char = SHOW NAMES | Y=yes N=no |
Y (yes) |
| 6th char = GALILEAN PREDICTION PERIOD | 0=24
hour 1=7 days 2=1 Month |
1 (7day) |
| 7th char = Galilean Timezone | 0=Universal
Time 1=Local Time |
1 (Local Time) |
| 8th char = Galilean Shortlist | Y=Ignore
invisible events N=List All Events |
Y
(events when Jupiter is down or Sun is up are ignored) |
| 9th char = Saturn Pointers | Y=yes N=no |
Y (yes) |
| 10th char = Track Real Time | Y=yes N=no |
Y (Track Real-Time on startup) |
To make this information clearer, the following chart may also help.
+---------1st char: Startup-screen.
| (0=skymap, 1=Jupiter, 2=Saturn, 3=Solar System
| 4=Ecliptic Circle, 5=Location-Input)
