1. The SITE command indicates the site name for data until the next SITE command.
2. The AZ_RESOLUTION specifies the azimuth resolution of the file. In this case it is 1°.
We expect to find 360 dierent azimuths in the file. Match this to your normal azimuth
resolution, though it finds the closest in any case.
3. The RANGE_RESOLUTION specifies the range step in km, and the total number of km
we are going to.
4. In this case, 1 km (0.6 mi) steps out to 300 km (186.4 mi).
5. Next is the AZ command, followed by the surface altitude in meters for each km in
range.
6. After 300 altitudes there is another AZ command and then possibly another SITE
command.

STAT: IRIS System Status
A STAT file contains a report indicating the state of all key components of the radar
software.
STAT (status) products are typically made on all IRIS systems that are critical to system
operation, such as the radar host, the product generator, and or critical display systems.
Instead of containing radar data, status products contain information about how well the
IRIS system is working.
These products are shown in the product output menu, and can be transferred to other IRIS
systems using the product output menu.
When transferred to another IRIS system, the receiving system becomes aware of faults or
problems with the sending system. For example, the radar-host status products are
distributed to most systems in a radar network, and the red-X is displayed on various
windows based on these status products.
The status product lists faults if any of the following occurs:
• BITEX critical faults
• RCP communication failure (RCP DEAD)
• RVP signal processor error
• IRIS internal critical fault. These are internal errors that are flagged as critical in IRIS.
