Dear all,

I updated the development version (v5.10c) on the Pluto web page. Mainly 2
bugs have been found and fixed:

1.) The decay angular distributions were implemented only for D+ and D++,
I added D0 and D- as well (this bug has been reported by V. Hejny)

2.) There was a severe bug in the angular distribution of all primary
particle productions (e.g. eta production): The angle has been re-sampled
for the primary particle but not for the additional daughters (This bug
affects only v5.10a+b)

Regards, Ingo Froehlich

Dear Pluto users,

I updated the pro version of Pluto (v5.1x) due to several bugfixes, most of
them are related to the angular distributions. One change fixed the pp elastic
sampling inside the deuteron. Moreover, the Delta decay was isotropic since
v5.11, this has also been corrected.

Please have a look into the release notes. Meanwhile the Pluto-link has been
moved, it is now visible on the bottom of the hades page (www-hades.gsi.de)

In addition, a new dev version was uploaded with many new (but preliminary)
features:
* PAngularDistribution has a new additional input: TGraph (for implementing
angular distributions from a publication/data points)
* The first tests for weight-based event sampling have been done (see pdf on
the web page)
* A batch-language allows for particle operations for histogram projections,
like boosting, combining masses and getting angles. Approx. 10x faster then
an (uncompiled) analysis macro.
* For the pn Bremsstrahlung, some adaptive mesh sampling method has been added
(multi-dimensional sampling needed for N+d/p+A/pbar+A interactions under
construction)
* The internal stucture has been changed that Pluto allows for different
models per decay (e.g., the generator, the weighting model, total cross
sections, ...)



Best regards, Ingo
