After the successful installation from the source code you may reduce the
disk space needed by OSA software by executing `make distclean' in the same directory where you executed
`make install'. This will reduce the amount of disk space needed to some 890 MB. You may additionally remove
the source code directories (support-sw, analysis-sw, contrib-sw). This will reduce the disk space needed to some 790
MB.
You will need approximately 10 GB of disk space to hold the data from one
day of INTEGRAL observations.
Memory/CPU : to actually run the software on observation data you will need at least some 500 MB of memory per simultaneously active user on your system. Although the software will run on slower systems, it is recommended to use systems with at least 500 MHz processors.
