From reading the documentation, I am not sure whether or not psfex has the capability to fit a single polynomial across chip gaps instead of completing an individual polynomial fit for each chip. To accomplish this, would I set NEWBASIS_TYPE=PCA_COMMON? Also, what is the difference between HIDDENMEF_TYPE and MEF_TYPE?
