System Requirements


CIAO is supported on a number of operating systems, which are listed on the Platform Support page. Certain system requirements are necessary to successfully install and run CIAO.


Linux

Memory and Disk Space

Chandra data files are large, which implies that certain processing and analysis operations will work more efficiently when they have access to large amounts of RAM. We recommend a minimum of 1Gb main memory. A full CIAO installation, including the background calibration files will require ~15Gb of disk space. The disk space for individual observations varies from a few megabyte to several gigabytes depending on the target as well as the exposure time and instrument configuration.

X11R6

X11, the X window system.

OpenGL

ChIPS requires OpenGL, an interface for system graphics. OpenGL is part of the xlibs development package.

gzip

The GNU zip package.


Apple OSX/macOS

Pre-built binaries are only available for 64bit, Intel OSX 10.9 (Mavericks), OSX 10.10 (Yosemite), OSX 10.11 (El Capitan) and macOS 10.12 (Sierra).

X11

X11 was included as an optional package in earlier versions of OSX; however, it currently must be installed separately from the XQuartz website. Users must be using XQuartz version 2.7.11 or newer.

Xcode

CIAO requires users have the Apple's Xcode tools installed on OSX/macOS. These tools are needed during the installation process to configure the programs to run on users machine.

Additionally, ChIPS requires OpenGL, an interface for system graphics. OpenGL is included in Xcode.

gzip

The GNU zip package.
