measuring the az,za dependence of birdies



Dates/datasets for az,za dependence data:

     The azimuth spins that have been done to measure birdie direction are collected here so that they can be compared. These spins also give an idea of the sidelobe response of the telescope from the direction of the birdie.

Az spin data sets:


az,za positions for various emission peaks

The table below shows the az,za positions where various emission peaks have been measured.
