[mesa-users] Evolutionary tracks interpolation

[Adrian Ayala]

Hi, everybody!

I'm trying to obtain isochrones by performing interpolation between 
several masses evolutionary tracks (from pre-main sequence to RGB tip). 
I'm finding some troubles, especially in RGB bump and tip regions. 
Interpolation does not work very well there. Could you suggest me some 
procedures, codes or tools to perform interpolation avoiding numerical 
errors?
Thank you in advance!
