Dear All,
As discussed at the software meeting today, the DC geometry in the CCDB 
default variation was updated with the so-called “installation” geometry 
that accounts for some changes of the chamber positions with respect to 
the original, pre-installation drawings. The DC geometry in the default 
variation now coincides with the one in the may_2018_engineers 
variation, which we have been using routinely for several months. This 
update removes the need of specifying the may_2018_engineers variation 
in running reconstruction.

As a consequence of this change, gemc 4.2.4 and older version, that used 
the old DC geometry, are now deprecated. The recommendation for all user 
is to use gemc 4.3.0, which implements the correct DC geometry. Users 
who may be interested in reconstructing old simulations Dione with gemc 
4.2.4 or older can use the CCDB variation dc_geo_gemc424 that contains 
the old, pre-installation geometry.

Note that chefs, who are processing real data with DC alignment tables, 
should continue using the specific variations that were created for this 
purpose.

Best regards,
Raffaella
