#****************************************************************************


# How to use this template
# ------------------------
# 1. Open this file with a text editor
# 2. File/Save As the file with YOUR script file name and the .cel extension
# 3. Change any of the commands or parameters to suit your needs
# 4. Add your own Script Body code


#----------------------------------------------------------------------------
# Set Celestia to a "known state"
#----------------------------------------------------------------------------

# Cancel follow and goto commands, and set Coordinate System to Universal...
    cancel { }

# Note: cancel in ver 1.3.0 does NOT clear Track, Lock or Chase, like the ESC key does,
#       so we must do it manually (version 1.3.1 does this automatically)...
#    select { object "" } # this works
#    track  { }           # this works
#    chase  { }           # this does not work
#    lock   { }           # this does not work


# Clear the display of any left-over text from the print command...
    cls { }


# Do not render the following objects...
    renderflags { clear "boundaries|comettails|constellations|eclipseshadows" }
    renderflags { clear "markers|orbits|pointstars|ringshadows" }
    renderflags { clear "automag|grid" } # version 1.3.1+


# Render the following objects...
    renderflags { set "cloudmaps|galaxies|nightmaps|planets|stars" }
    renderflags { set "atmospheres" } # version 1.3.1+


# Do not label the following objects...
    labels { clear "planets|moons|spacecraft|asteroids|constellations" }
    labels { clear "stars|galaxies" }


# Label the following objects...
#    labels { set "planets|moons|spacecraft|asteroids|constellations" }
#    labels { set "stars|galaxies" }


# Unmark any objects that are currently Marked and disable Marker display...
    unmarkall { } # version 1.3.1+


# Set Minimum Orbit Size...
    set { name "MinOrbitSize" value 1.0 }


# Set Ambient Light Level...
# (0.0 to 1.0 is a good Lo-Hi range)...
    set { name "AmbientLightLevel" value 0.10 }


# Set Field of View...
# (Celestia 1.3.0 default value is 45)
# (Celestia 1.3.1 default value is 25)
    set { name "FOV" value 25.0 }


# Set Star Distance Limit...
# (Celestia default value is 1000000)
    set { name "StarDistanceLimit" value 1000000 }


# For the next two Magnitude settings, Selden Ball reminds us of the following:
# "A magnitude limit of 6.5 corresponds to what you can see with the naked eye
# on a very dark night away from city lights."

# Set visible star Magnitude...
# (Celestia UI: 0.8 to 15.2, default is 6.0)
    setvisibilitylimit { magnitude 6.50 }


# Set Faintest Auto-Magnitude Brightness...
# (Celestia default value is 8.5)
    setfaintestautomag45deg { magnitude 8.5 }


# Set Time Rate (1x, 100x, 1000x, etc.)...
# (A negative value = Reverse Time
#               0   = Pause Time
#               1.0 = Real Time (default)
#            1000.0 = Good moon orbit motion)
    timerate { rate 1.0 }


# Set Date and Time...
#     U.S. Navy Calendar Date/Time to Julian Date/Time converter:
#       http://aa.usno.navy.mil/data/docs/JulianDate.html
#   time { jd JulianDay.JulianTime }
