Another question about RA in stc files...
Posted: 14.10.2002, 06:00
Sems like this is a bit off in the stc files...According to the stars.dat format RA is computed like so...
Right Ascension is specified in hours, so 12h 30m would be 12.5.
So now when I look at the code for Sirius B it tells me RA is ~101
# Sirius B
300001 {
RA 101.2886
Dec -16.71314306
Distance 8.601223
SpectralType "D"
AppMag 15
}
How can this be if there is a max of 23.999h?
Sirius actual RA is 06 h 45 m and Sirius B should be just a tad off from that...so Im confused how this is set up in stc files...If anyone could clarify this for me it would be greatly appreciated...
