Beginning and ending dates
Posted: 20.12.2005, 04:53
I was working on my Mira (variable star) & companion w/ accretion disk tonight and had a mini brainstorm. What if you could port/parse variable star data in from the AAVSO tables with historical dates and magnitudes into an stc file. Oh great idea, until I came to the question
"Can stc files contain beginning and ending dates?"
I haven't had any luck getting it to work...
As a side note, for future versions of Celestia. How difficult would it be to put a period of variability and range of magnitudes or rather spectral type into the program. For instance.
Barycenter "MiraAB"
{
RA 2.32241 # 2:19:20.7 (h:m:s)
Dec -2.9775 # -2:58:39 (deg:m:s)
Distance 418
}
1 "MiraAB A" # component Omicron Ceti HD 14386
{
OrbitBarycenter "MiraAB"
SpectralType "M7IIIe"
AbsMag 1.1 #actual variation -2.5 to 4.7
VariabilityStart "1605 01 01 12:00:00 AM"
VariabilityPeriod 331.96 #in days
VariabilityAbsMagLow 4.7
VariabilityAbsMagHi -2.5
Radius 480e6
SemiAxes [1 0.85 1]
EllipticalOrbit {
Period 1e10
SemiMajorAxis 1e-9
}
}
