09apr21 Crosses on the Crab


update: 19apr21.. the glitches were created by the sband portion of the signal overdriving things.


   On 09apr21 9 crosses were done on the crab nebula. The setup was:

Processing the crosses

    For each cross a 2d gaussian was fit to the total power data for each 172MHz Freq band.

The fit used was:

Plotting the results

Over plot  the azimuth strips for the 7 frequency bands from 1 cross (.ps) (.pdf)

 Plot the azstrips data and fit at one freq band for all  9 patterns. (.ps)  (.pdf210409_crosses_crab_2.pdf)

Plot the fit parameters vs elevation (.ps) (.pdf)
