This Occult 4.1.1 is based on a number of incremental additions or changes, as well as numerous bug fixes. The following is a summary of notable changes introduced into Occult 4.1.1.0 since version 4.1.0.0.

A full list of the program changes is provided in Occult under the menu item Program updates - List version changes

HOW TO OBTAIN OCCULT v4.1.1

Download the files shown below by right clicking on the filename and doing a "save as". Then 'run' occult4 installer.msi (or Setup.exe for old versions of Windows).

FIRST TIME INSTALLATION INSTRUCTIONS AND NOTES

Occult v4 has been written in the language C#, and runs in the .NET framework. To run Occult you must have the .NET Framework V2 or later installed on your computer. The .NET framework is included with Vista, Windows7 and Windows8. If you are using an older version of Windows you may need to download the .NET framework from the Microsoft Download center here. Or do a Google Search for Net Framework V2 to get the download site from Microsoft. If you have been running OccultWatcher, you have the .NET framework installed.

The files you need to download are (use right click on your mouse and do a "save as"):

These files install a functional version of Occult 4 (limited only by the absence of certain data files, some of which are large). Either run occult4 installer.msi, or put these two files in the same directory and run Setup. The default installation path is \Occult 4. Vista, Windows7 and Windows8 Users should avoid installing the program in the Program Files directory - to avoid issues with the User Account Control security system in Windows.

When you first run the program, you will be taken to a page that displays a range of default settings. You can change the settings here at any time after Occult has been installed. However at this stage you should do the following:

You will then be taken to the download page, where you can download the latest versions of a number of data files - including some large catalog files. The files that need to be downloaded will be tagged with a chevron. However you do not need to download them immediately.

Finally you will be taken to the main form of Occult, where you can use its functionality.

To assist you in learning how to use the program, the Help file system includes a number of first time user topics. You should work through these examples - to become familiar with how the program works, and the functions that are available.

HOW TO UPDATE OCCULT

When you run Occult, the existence of updates will appear at the bottom-left of the main form. To update, simply click the update text. The frequency at which Occult will check for updates is set in the User Settings, which are accessed from the Maintenance tab of Occult. You can manually check for updates using the Menu item Program updates...

If for some reason you need to do a manual update of the program files

COPYRIGHT ISSUES

Occult relies heavily on data that is freely available. Items such as various star catalogues and the planetary ephemerides have been developed by government funded agencies or grants. Occultation and graze observations have been contributed mainly by the efforts of amateur astronomers (or as I prefer to call them, unpaid astronomers) from around the world. This contribution needs to be recognized and acknowledged.

The philosophy behind my writing and maintaining Occult is to encourage useful observations of occultation phenomena, thereby increasing our knowledge of the world around us. Accordingly:

For the record, I reserve all rights to the Source code and any decompilation thereof - but with IOTA being able to continue to maintain/improve the program on the same basis as above, when I am no longer in a position to do so.
