Here is --just picked up on Mikey Brass' "Paleoanthro" list -- an announcement that should be of interest to many Forum members:
Subject: new 14C calibration curve - CalPal-2007-Hulu

Dear collegues, friends, and CalPal-users,
a while ago you have downloaded the
Cologne Radiocarbon Calibration & Palaeoclimate Research Package CalPal
and registered at
www.calpal.de <http://www.calpal.de/> .
We are pleased to announce a new CalPal version, ready for download.
In case you recieve repeated mails, we apologize.
CalPal contains an update of the 14C-age calibration curve, called
CalPal-2007-Hulu,
based (along with other data) on corresponding Hulu-referenced,
i.e. U/Th-based Cariaco data by Konrad Hughen et al. (QSR, Vol 25, 2006).
CalPal-2007-Hulu is installed as the default 14C calibration curve
in the two program versions CalPal (
www.calpal.de)
<http://www.calpal.de> and CalPal-online (
www.calpal-online.de)
<http://www.calpal-online.de>.
The different algorythms used in these programs may be responsible
for slightly divergent numeric output data.
To support application of the new Hulu 14C-age calibration,
we have included in the CalPal climate-library some ready-tuned HULU-scaled
Greenland and Antarctic ice-core climate proxies,
and also the necessary synchronisation tables (GISP2->Hulu;
GRIP_SS09->Hulu> NGRIP->Hulu)
for age-transfer of further climate data, if needed, using the CalPal
climate age-model dialog.
The radiocarbon database for the Near Eastern and Mediterranean Early
Neolithic is also updated,to include the North European Trichterbecher and Ertebölle cultures
(total: N=9715 dates).
We have integrated the INQUA Palaeolithic Database (courtesy Pierre
Vermeersch),
with N=5900 dates. Further revisions and updates can be taken from the
CalPal change-log
http://www.calpal.de/calpal/update.htm .
Again, thanks to many collegues for support!
With kindest regards,
Uwe Danzeglocke, Bernhard Weninger, and Olaf Jöris
