ACS 1.3

• acs-1.3.tgz (roughly 500 Mbyte)
  
• acs-lite-1.3.tgz (roughly 20 Mbyte)
• ACS 1.3 presents the new version of our introductory volume Moving Stars Around, which is now completed.

• For instructions to install the computer codes on your own computer, see the README page.

ACS 1.2.5

• acs-1.2.5.tgz (roughly 400 Mbyte)
  
• acs-lite-1.2.5.tgz (roughly 15 Mbyte)
• ACS 1.2.5 presents only minor changes with respect to the previous version. The new version of our introductory volume Moving Stars Around is in better shape now, with the first 15 chapters now close to their final form.
• For instructions to install the computer codes on your own computer, see the README page.

ACS 1.2.4

• acs-1.2.4.tgz (roughly 400 Mbyte)
  
• acs-lite-1.2.4.tgz (roughly 15 Mbyte)
• ACS 1.2.4 presents only minor changes with respect to the previous version. The main addition is the first part of the new version of our introductory volume Moving Stars Around. We have also added a section of Links to Literature and Related Projects to our home page.
• For instructions to install the computer codes on your own computer, see the README page.

ACS 1.2.3

• acs-1.2.3.tgz (roughly 400 Mbyte)
  
• acs-lite-1.2.3.tgz (roughly 15 Mbyte)
• ACS 1.2.3 presents only minor changes with respect to the previous version. The main addition is our new time-symmetrized individual-block-time-step code. As far as we know, this is the first code that succeeds to apply froward-backward time symmetry to an individual time step code with block time steps, i.e. with time step sizes only allowed to be different from each other by integer powers of two.
• For instructions to install the computer codes on your own computer, see this README page.

ACS 1.2.2

• acs-1.2.2.tgz (roughly 300 Mbyte)
  
• acs-lite-1.2.2.tgz (roughly 15 Mbyte)
• ACS 1.2.2 presents a new lay-out of the ACS home page, which reflects our latest thoughts about the structure and evolution of our ongoing projects of development of simulation code and documentation.
• The Maya Project is the new name for what we used to call the Kali project. Maya is now the name for the software environment within which we will run the Kali code, which will be our flagship integrator for simulating dense stellar systems. While Maya will denote our virtual laboratory, Kali will be our main laboratory tool.
• We have started to rewrite our very first volume, Moving Stars Around, to bring it in line with the Maya project. Specifically, we will use a much more flexible plotting package, we will introduce a visualization tool, and all codes will be written in Ruby.
• We have a revised five-year plan for the Kali code development.
• In addition, again a large number of small corrections have been made.
• For instructions to install the computer codes on your own computer, see this README page.

ACS 1.2.1

• acs-1.2.1.tgz (roughly 200 Mbyte)
  
• acs-lite-1.2.1.tgz (roughly 15 Mbyte)
• ACS 1.2.1 presents the first part of what will be a new volume, 16. N-Body Experiments: Orchestrating and Analyzing Multiple Runs
• We have drawn up our first five-year plan for the Kali code development.
• In addition, a large number of small corrections have been made.
• For instructions to install the computer codes on your own computer, see this README page.

ACS 1.2

• acs-1.2.tgz (roughly 200 Mbyte)
  
• acs-lite-1.2.tgz (roughly 15 Mbyte)
• A novel feature of ACS 1.2 is the presentation of an N-body code that allows individual particles to use not only individual time steps, but also individual integration algorithms, from a wide range of choices including ... (more)
• For instructions to install the computer codes on your own computer, see this README page.

  • postscript and pdf files, that were left out inadvertently from ACS 1.0

ACS 1.0

It contains the versions, at that time, of the first four volumes of the Kali project, together with the first volume of the Open Knowledge umbrella project. In addition, the older volume Moving Stars Around, is included. In total, this release contains the equivalent of roughly 700 pages of printed text, together with the computer codes developed in the text.

We are making all releases presented here available under the conditions of our ACS open source license.

We present ACS 1.0 in two option, each as a single tar file:

• acs-1.0.tgz (roughly 100 Mbyte), containing
  • all html files present on the ACS web site at the time this version was released
  • postscript and pdf versions of the text files
  • all computer codes discussed in the text
  • additional codes that are used for generating the .html, .ps, and .pdf files from the original .ok files
  
  
• acs-lite-1.0.tgz (roughly 15 Mbyte), containing
  • a few top-level html files
  • all computer codes discussed in the text
  • the .ok files and codes that allow automatic construction of the .html, .ps, and .pdf files, with the exception of those connected with the MSA volume.
