APPM --- strange point values in a model


Dmitri
 

Hello,

I ran APPM for the first time.  Over all there were 47 points and all were plate solved just fine.
The differences between assumed RA,DEC and what plate solving showed were in  [-15,15] arc-min for all but one point. Which showed the differences -5263 arc-min in RA and 2706 arc-min in DEC.
Looking at pairs coordinates they should be about 1 arc-min and 6 arc-min (below is part of APPM log corresponding to this point).  Such big reported differences look like an error.  I am wondering if this point will adversely affect the pointing model.

Should I just remove the point from the model?
Is this a bug in APPM that affects modeling or it affects only visual presentation of mapped points?
