Hi everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I found some useful code to predict limb darkening coefficients on http://www.fiu.edu/~vanhamme/limdark.htm. I understand all of the inputs to this program except the selection of 'bandpass'.

I am assuming that any one bandpass refers to a range fo wavelengths for which the calculation of the limb darkening coefficients will be valid. Can someone please just first confirm that this interpretation is correct?

Secondly, the author uses names such as Hipparcos, Tycho B and V bands which don't really mean anything to me, so I need some kind of catalogue or index which gives the corresponding wavelength values in S.I. for each bandpass name. If anyone knows what these names refer to or a good online catalogue or something, please please post it!

Thanks in advance,

Natski
