From: Frank Grundahl Jensen Subject: Open cluster images To: bedding@Physics.usyd.edu.au Date: Mon, 17 Apr 100 14:35:56 +0200 (METDST) Hi Tim, I have put two images with their respective photometry files (plus a .ps plot) of M67 in the directory /ai11/grundahl/tim [ on origo] The photometry is not matched up, so the students may need to write small programs to match up the photometry after they have derived the positional transformations between the two images. For your reference the transformation follows below: X(4763) = A + C*X(4671) + E*Y(4761) Y(4763) = B + D*X(4671) + F*Y(4761) ------------------------------------------------------------------------ A B C D E F ------------------------------------------------------------------------ dfsc4761.alf 0.000 0.000 1.00000 0.00000 0.00000 1.00000 dfsc4763.alf 1.837 3.502 1.00010 -0.00003 -0.00005 1.00020 ------------------------------------------------------------------------ Best regards, Frank
