Description
Programming language is Fortran 95. Operating system is Win10/11. CalPal has a standard Graphic User Interface (GUI) that makes extensive use of the Winteracter Fortran-language toolset which also supports 14C-database Excel Import/Export and chronological screen measurements. The IMSL-Libraries are used for mathematical and statistical data processing.

Abstract
Installation: Download CalPal_A_Edition_2025_11.exe and unzip to a directory of your choice (e.g. ‘c:\test1’). The installation then runs via double click on ‘Setup_Calpal.exe’.
General Description: CalPal supports the cultural and palaeoclimatological analysis of chronological data from 'mixed' dating methods/sources. The analysis allows both automated inter-method (e.g. 14C, Dendro, Historical, OSL, TL), as well as automated intra-source switching (14C: N-S Hemisphere, Marine & Reservoir Corrections) of the input ages. The necessary (quality-control) test-results of such multi-method applications (termed: Calibration Curve Switching: CCS) for the different CalPal-dialogs are provided in the file 'CalPal CCS Interdialog Comparisons.pdf'. Numeric calibration curve comparisons are provided in the file named 'CalCurveComparisons_2020.pdf'. These comparisons range from IntCal04 through Fairbanks 2005, CalPal-Hulu-2007, IntCal09; IntCal13, up to IntCal20. The CalPal Database (Excel) now contains a total of 196171 dates (for 12 ‘Continents=Excel Spreadsheets)’, 206 countries, 34522 sites), with 98% georef.
The main amendments in CalPal Edition 2025.11 are:
- Substantially modified dialog “Reservoir Explorer” for construction of Archaeological Chronologies and for automated Calibration Curve Construction.
- Modified dialogs “Correspondence Analysis & Pottery Series”, with added CA-projects
- Reworked mouse-based screen-age measurements in all dialogs
- Updated Calibration Curve (INTCAL20.ext2) with added annual data for the Mediterranean Iron Age (Brehm & 2025; N=856); recent Miyake & Solar Excursion data)
- Extended Climate Library. N=587 records (14 Treeview Branches)
- Extended Mediterranean Iron Age Library. Links to N=97 papers (6 Treeview branches)
