Orders don't appear centred on numax

[alexlyttle]

Issue

Using the star class, running run_asy_peakbag(norders=6) does not appear to centre the orders chosen on the given numax (numax ~ 1190 muHz) as seen in this image (note this fit may not be right anyway!):

I had noticed this issue in a few other stars, although it wasn't as obvious as most of the time I have ran with norders=8. Here, however, it appears to miss some possible higher frequency modes.

Suggestion

Is this the intended behaviour? If not, this could be a bug in how the modes are chosen about numax, I will have a little look in the code in case I spot something.

@alexlyttle Thanks for highlighting this. Yes we need to look at this. It's possible that it is related to the input Dnu and numax and is possibly a limit of the the current knowledge. It's also possible it's a bug! I think we should have a look this and decide if it is a bug or not. @nielsenmb is very good at finding bugs in my code ... ;)
