================

 

The files in this directory are for installing the latest version 3.0.0 of AstroImageJ on Linux, Windows, and Mac operating systems. The files are complete and do not require a previous installation of ImageJ or AstroImageJ.

 

If you already have installed version 2.0 of AIJ, simply use the update option on the AIJ toolbar 'Help' menu to upgrade to 3.0.0.  The user will need write permission to the directory where the software is installed. 

 

For more information and help, please see the AstroImageJ user forum on nabble:

Once you have installed this version, use the Update feature under the Help menu to install the latest changes.

 

Mac OS X Installation

=====================

 

Download and unzip AstroImageJ_3.0.0_20141206_mac.zip and copy the AstroImageJ folder to the applications folder. Double-click AstroImageJ.app on 32-bit systems or AstroImageJ64.app on 64-bit systems.

 

Since OS X 10.7 (Lion), Java is no longer pre-installed so you are prompted to install it the first time you install a Java application. When you see the message "To open AstroImageJ64.app you need to install the legacy Java SE 6 runtime", click 'More Info...' to download and install Apple Java 6 on your machine. After the download completes, open the Downloads folder and double-click the JavaForOSX2014-001.dmg file. The double-click JavaForOSX.pkg and follow the instructions on the screen to complete the package installation.

 

With OS X 10.8 (Mountain Lion), you may get the message "AstroImageJ64 is damaged and can't be opened". To work around this problem, go to System Preferences ->Security & Privacy -> General and set "Allow applications downloaded from:" to "Anywhere". You can restore the original setting once AstroImageJ is running the first time.

 

AstroImageJ does is not compatible with Oracle Java 7 on OS X versions at this time.

 

You may need to increase the amount of memory allocated to AIJ using AIJ_Toolbar->Edit->Options->Memory & Threads. Enter the amount of memory in MB that you want allocated to AIJ. It is recommended to NOT exceed 2/3 of the physical memory installed in your system. For example, if your machine has 8 GB of memory, enter a memory

size up to ~5500 MB.

 

Click "OK" and close AIJ. Restart AIJ to use the new memory settings.

 

Finally, upgrade to the latest version of AIJ by using the built-in update feature. Go to AIJ_Toolbar->Help->Update AstroImageJ. The "Upgrade To:" box will default to the latest version of AIJ. Click "OK" and three files will be downloaded and installed in the proper location in the installation directory structure (again, you need write access to the installation directory). After the files have been installed, AIJ will automatically close.

 

Restart AIJ to use the updated version.

 

From now on, AIJ can be started by double-clicking either AstroImageJ.app or AstroImage64.app. Either app can be dragged to the Dock to provide convenient access for starting AIJ.

 

DONE!
