[34.08] Research Experience for Teachers at NRAO--Green Bank. Calibrating Array Detectors.

V.F. Pereira (NEST+m), B.S. Mason (NRAO--Green Bank)

Realistic simulations of the sky, that include spread in detector gains, telescope pointing errors, detector and sky noises, were used as an input, for an algorithm developed by Fixsen, Moseley and Arendt to analyze sky data. Results of this algorithm were then compared to another algorithm in which pixel gains were calculated assuming that the contribution of the atmosphere is constant. Preliminary results indicate that the Fixsen, Moseley and Arendt algorithm produced better images of the sky as measured by noise and maximum signal to noise ratio. Finally, a lesson plan based on this summer experience is presented.
