sol?s luminosity

Post #1by Tosv » 02.08.2004, 20:14

The sun?s luminosity (upper left corner of the screen) is calculated to 0.999x sun. Isn?t the correct value 1.000?

This has been brought up several times in the past, so obviously it is a platform-specific rounding error or some other kind of hard-to-fix problem. :(

Okay.
I don?t know if this will helps but I have the same symptom on both my home-computer and my computer at work.

Home:
Celeron 333 MHz
Win ME
No 3D-hardware (an old Cirrus Logic-card that came with the computer).


Work:
Celeron 1 300 MHz
Win XP sp1
Intel 82810E Graphic?s Controller (according to sysinfo tool AIDA 32)


By the way. Is this a problem that affects all stars or is it limited to the sun?

It's effectively a non-problem for other stars, since we don't know their luminosity to an accuracy of one part in a thousand anyway.
