Check on recorded nominal vs center position for agc_match table

yuki.moritani reports that the nominal and center positions in the agc_match table appear to be swapped. Also looking briefly at it, the flags column does not seem to be properly populated for the non-matched identified stars.

I wonder agc_center_x_mm (and y) and agc_nominal_x_mm (and y) has been flipped?
For duplicated stars, the agc_match table shows the same value for agc_center , and different values for agc_nominal And if I convert pfi-mm to ag-pixel, agc_nominal seems match to measured position. Could you check this too?
