| Description |
|
In the Nov. run, it was found that the predicted position of the same stars moved on PFI coordinates, even PA was fixed. It seemed that the position rotated w.r.t the time. I found that the rotation direction of the coordinates is inversed for transformation b/w the telescope and PFI. |

I tested the code with some published pfsDesign file and AG images during Nov run, and modified code works OK now. (Predicted position slightly shifted from actual positions, but it will be modified after we take a look distortion further.) |
