      will now be in ns, too.
 
+   - star: is now calculating a new timing parameter the Slope along
+     the major and minor axis of the shower. Therefore a numerical
+     solution of a line-fit is used. To use MHillasExt.fSlopeLong
+     and MHillasExt.fSlopeTrans don't forget to multiply it with
+     the sign stored in MHillasSrc.fCosDeltaAlpha as usual.
+
+   - ganymed: The old hadronness and size cuts have gotten new indices
+     (10, 11). The old indices 8 and 9 now mean an additional condition
+     for ghostbusting based on the formula (dist-c[9])*c[8]-slope.
+     If you want to switch off this cut just move the line far away enough,
+     e.g. by setting c[9] to -500. Please update your ganymed.rc files
+     accordingly!
+
+   - ganymed: The old Cut0 is now called CutQ and is calculated before
+     the source position is caluclated. If you need a quality cut
+     including source dependant data (be very carefull with this!)
+     you have to use Cut0 instead.
+
+   - ganymed: now properly supports three off regions in wobble mode.
+     It will be the default from now on in ganymed_wobble.rc. To change
+     the number of off-regions use
+         NumOffSourcePositions: 1
+     in your ganymed.rc. Also by default no off-theta cut will be done
+     anymore so that you will get a background level higher than the
+     signal level in your ThetaSq plot for ThetaSq>0.2.
+     (Rem: ThetaSqN is no longer needed)
+
    - ganymed: From XXXX on a real starguider calibration with a real
      pointing model for the starguider is done.

    - ganymed: was broken for Wobble-MCs... fixed.
 
-   - optim: MHThetaSqN can now also be used in teh optim-macros (if
-     you use MFMagicCuts, which are necessary to calculate Disp).
-     Just replace
-         MJOptimizeCuts opt("MHThetaSq");
-     by
-         MJOptimizeCuts opt("MHThetaSqN");
-     And make sure to switch off your theta cuts:
-         cuts.SetThetaCut(MFMagicCuts::kNone);
-     and set the scale mode correctly
-         fit.SetScaleMode(MAlphaFitter::kNone);
+   - optim, sponde: should now properly support three off-regions.
+     Just produce your ganymed summary files with three off-regions.
+     optim and sponde will automatically get all off events from
+     all off-regions from this file. Please do not forget to
+     set the scaling in optimwobble.C properly:
+        fit.SetScaleMode(MAlphaFitter::kNone);
+        fit.SetScaleUser(1./3);
+     it is not yet read in automatically (will follow soon)
