Version 1.6.2 of Duchamp is now available [26 September 2017]. It can be downloaded in source format, in a gzipped tar archive. The code will need to be compiled on your local machine: a configure script and a Makefile are provided to make this as easy as possible.
This release contains a number of patches accumulated during ASKAPsoft development, as well as a fix for an error when plotting spectra (with spectralMethod=peak). The sizes of ellipses written to the karma annotation files have also been fixed. For further details of these changes, consult the CHANGES file.
Three external libraries are required (in addition to the standard C/C++ libraries): PGPLOT, CFITSIO and WCSLIB. It is possible to compile Duchamp without having PGPLOT on your system: you just won't get any of the nice useful graphical output. See the README file for complete information on installation of Duchamp.
Changes from the previous version can be seen here (this file is included in the tar archive), while the archive files and documentation from the previous release versions are here, if you are really interested.
I'm always keen to hear from people who have used Duchamp, especially if they have comments on the way it works or suggestions as to how it can be improved. I may not have been thinking of your particular application when I wrote it, so if it doesn't do something you think it should, let me know!
There is a mailing list duchamp-user<at>atnf.csiro.au that users of Duchamp can subscribe to. This will be used to announce updates to the code and any other general issues. All messages will be archived here.
