DAOPHOT recenter option

Dear all,
Standard version of DAOPHOT includes two possibility to recenter star positions during fitting: 1) when we turn on the option "recenter=yes" positions of all stars are fitted; 2) in the case "recenter=no" all positions are kept fixed at their initial coordinates. I would like to realize another possibility - to recenter the frame position as a whole including its orientation and keep the distances between stars. Anybody have some idea how to realize that scenario without directly changing of a source code?
Best regards,
Vyacheslav Shalyapin

Hello Vyacheslav,
There is no way to have DAOPHOT do what you suggest without serious code changes. However, you might be able to accomplish the same thing with a script where you take the x and y positions from the database and shift and rotate them and then create a new input to DAOPHOT with the corrections. Then you would use the no recentering option to force the photometry at the positions you corrected.
I hope this helps.
