Hi Paul,

Had a look at your FIT text file.

It's just all noise. There is something random going on. And not random
in a systematic way, like non-orthogonality. Random as in throw the dice random.
However, the good news is that the results are telling us that, so it is still good information.

Adding additional terms won't help at this stage.
Could you please show the results from the following fit commands? (i.e. the fits text files including as you did before).

1) ID & IH only
2) ID, IH, MA, ME only
3) ID, IH, MA, ME, NP & CH only

Could you please also supply the scatter diagram that results from each of the above fits.

Knowing the results from the above might be able to tell me more.
However it could well be a case of 'garbage in, garbage out'.
For example, few things will throw out the results more than incorrectly identified/mapped stars.

What would also be useful is if you could do a File Text Export command and post the text file.

Based on the FIT text file you have already posted, the fact that the sigmas
are nearly as large as their corresponding terms tells me that it is noise.
The MA and ME terms are also giveaways.
These two terms have very distinctive mathematical signatures and are thus
normally not strongly correlated to other terms. But they too show that
something random is likely to be occurring.
