 // Lid is closed. (< run 84980)

+// Mirror refocussing around 4.Aug.2007, from the Runbook:
+//
+// [2007-08-04 04:46:47]
+// We finished with the focussing with Polaris. The images need to be
+// analysed and new LUTs generated.
+//
+// [2007-08-04 23:47:30]
+// Actually we see that the mispointing is always large; probably since
+// the LUT tables have not yet been adjusted to the new focussing.
+//
+// [2007-08-03 23:07:58]
+// Data taking stopped. Mirror focussing.
+//
+// [2007-08-05 00:09:16]
+// We take some pictures on stars nearby Cyg X3 with the sbig camera;
+// actually the spot doesn't look very nice... The pictures have been
+// saved with name Deneb- and Sadr- Polaris seems a bit better. Should we
+// have new LUT tables after the focussing?
+//
+// [2007-08-10 20:18:48]
+// Tonight we take first images of Polaris with a new LUT file generated
+// based on the recent focussing. The image will be analysed tomorrow and
+// than new LUTs will be generated. For tonight the focussing is still not
+// changed.
+//
+// [2007-08-14 20:57:59]
+// The weather is fine. There is a group of hobby astronomers at the
+// helicopter parking. Before data taking, we tried to check the new LUTs.
+// However, because of technical problems with the new LUTs we had to
+// postpone the measurements. We lost some 10 min of data taking because
+// of this.
+//
+// [2007-08-14 22:29:37]
+// Before continuing the observation we perform a focussing test with the
+// new LUTs from recent Polaris focussing. Note: Data on Her X-1 was taken
+// with old focussing. We performed PSF measurements on Kornephorus (Zd
+// 31.77, Az 264,67) first with old LUTs and then with new LUTs. We took
+// T-points with both focussing. The first T-Point corresponds to the
+// previous focussing and the second with the improved. Please check both
+// T-points for eventual misspointing. We found big improvement of the PSF
+// with the new LUTs and will therefore continue from now on with the new
+// focussing. Having a first look at the SBIG pictures we see a slightly
+// misspointing of ~0.1 deg with the new LUTs.
+//
+// [2007-08-14 22:46:10]
+// Comparing the trigger rate with yesterday night we do not see an
+// improvement with the new focussing.
