Summary

Intro:

    We use crosses on sources for the system performance and pointing model. For the 12 meter they are:

    For model 3A i just fit 1d gaussians to each az and el strip.

    Using a 2d gaussian fit will:


The 2d gauss fit:

    The 2d gauss fit is:


Examples of 2d fits to 3C405 (Cygnus A):

    Sband crosses (@ 2270 Mhz) on 3C405 were used to check the 2d gauss fitting.

The plots show the results of the 2d gauss fits (.ps) (.pdf)
