KRC differentiates daily eclipses, such as those experiences by Galilean satellites, from rare eclipses, for example partial solar eclipse by Phobos as seen from the surface of Mars.
Contents |
[edit] Daily Eclipses
Daily eclipses are recurring events modeled identically for each day of the year. To include a daily, eclipse, a few parameters must be specified:
- Eclipse #forces an eclipse (Default = "F")
- Eclipser #Eclipser name, for example "Mars" for a Phobos or Deimos study
- Ecl_Cent_Hr #Eclipse central hour [0-24]
- Bias #Eclipse Bias (0 => perfect alignement; 1 => partial eclipse); see below for a graphical definition of Bias
- Eclipse_Style = 1 #=1 Forces daily eclipses
- Date #[ J2000 date of Rare eclipse ] Unused by the KRC for rare eclipses (but required / need to test?)
Example: include a solar eclipse by Mars on Phobos using standard Phobos/Mars orbital properties:
- Eclipse = "T" #forces an eclipse (Default = "F")
- Eclipser = "Mars" #Eclipser name
- Ecl_Cent_Hr = 12. #Eclipse central hour
- Bias = 0.0 #Eclipse Bias (0 => perfect alignement; 1 => partial eclipse)
- Eclipse_Style = 1
- Date = 0.
out = krc( lat=12.,INERTIA=50.,body="Phobos",LKofT="T",Eclipse=Eclipse,Eclipser=Eclipser,Ecl_Cent_Hr=Ecl_Cent_Hr,Bias=Bias,Eclipse_Style=Eclipse_Style,Date=Date)
When working with eclipses, it may be beneficial to increase the time resolution of the output by increasing N24
out = krc( lat=12.,INERTIA=50.,body="Phobos",LKofT="T",Eclipse=Eclipse,Eclipser=Eclipser,Ecl_Cent_Hr=Ecl_Cent_Hr,Bias=Bias,Eclipse_Style=Eclipse_Style,Date=Date,N24=96*100)
[edit] Rare Eclipses
Rare eclipses are one time events. To include a rare, eclipse, a few parameters must be specified:
- Eclipse #forces an eclipse (Default = "F")
- Eclipser #Eclipser name, for example "Mars,Phobos" for a partial solar eclipse by Phobos
- Ecl_Cent_Hr #Eclipse central hour [0-24]
- Bias #Eclipse Bias (0 => perfect alignement; 1 => partial eclipse); see below for a graphical definition of Bias
- Eclipse_Style = 2 #=2 Forces rare eclipses
- Date #[ J2000 date of Rare eclipse ]
