Grinder - IRAF

As of this writing, the control room software is based on IRAF. IRAF is a now largely obsolete collection of software that was extremely popular in the 80's and 90's in the astronomical community. Today it is largely abandoned. The staff at NOAO that once supported it have either retired or lost interest, and much of the astronomical community is now busy writing code in Python. Even Pyraf, which was a set of python bindings to the IRAF tools has fallen by the wayside.

Be all that as it may, the oven software we use is based on IRAF. In fact it is an IRAF extension or package and can only run inside of IRAF. The software is written in a mix of SPP (a unique FORTRAN dialect) and C. Details on this can be found elsewhere.

IRAF versions

Our old suns run the following version:
NOAO Sun/IRAF Revision 2.11.3 Thu Feb 10 22:45:18 MST 2000
This is the EXPORT version of Sun/IRAF V2.11 for SunOS 4 and Solaris 2.7
And for the record, the old suns run the following (Solaris 8).
version
Machine hardware:   sun4u
OS version:         5.8
Processor type:     sparc
Hardware:           SUNW,Ultra-5_10
Our modern linux machines run the following version of IRAF:
NOAO/IRAF PC-IRAF Revision 2.16.1 EXPORT Mon Oct 14 21:40:13 MST 2013
This is the EXPORT version of IRAF V2.16 supporting PC systems.

Running the oven software

Two IRAF packages are significant. These are "mirror" and "scopes". Mirror is the official oven control room software. Scopes is John Hill's catch-all package, the item of interest in it is the "furnace" sub-package. This is a big collection of scripts to graph data, as well as a lot of unique and important documentation in the form of help files. More on both of these elsewhere.
