Kitt Peak Multi-Tasking FORTH-It

An overview of the Kitt Peak National Observatory (KPNO) real-time environment is presented. The eleven optical telescopes at Kitt Peak employ a variety of experimental instruments, including Fourier Transform Spectrometers and large array digital cameras, that impose a diverse set of real-time requirements. Presented next will be a historical perspective of FORTH and KPNO over the last decade ...

The McMath Solar Telescope of Kitt Peak National Observatory

The mechanical and optical arrangement of the 160-cm aperture, 90-m focal length, McMath Solar Telescope is described. Efforts have been made to obtain good images by thermal control of the optical paths and by selection of fused quartz or metal-based mirrors for the optical components. The optical paths and performances of a vacuum double-pass spectrometer and single-pass spectrograph are illu...

WIYN to Operate the Kitt Peak 0.9-meter Telescope: NOAO Users to Gain Continuing Access to Mosaic

A panel of reviewers met last September to review proposals submitted to operate the Kitt Peak 0.9-m telescope. They found that the proposal submitted by the WIYN Consortium was superior in the opportunities it offered for scientific research and education, as well as in the management of refurbishment and operations. As of this writing, agreements with AURA and NSF are in the approval process....

Control of Complex Peak-to-Peak Dynamics

The paper illustrates a method for the design of suitable controllers of chaotic systems characterized by complex peak-to-peak dynamics, namely by a recursive relationship between consecutive peaks (relative maxima) of a scalar output variable. For such systems, a reduced model can be defined which, in general, is a hybrid model composed of a one-dimensional map and a finite-state automaton. Th...
