The pulsar, B1133+16, was observed on the 60 ft dish antenna by Rich Russel and Ray Uberecken after 4 hours of tracking and collecting data on the pulsar.
This pulsar is the weakest object observed by DSES at 0.257 Janskys!
The pulsar is noted for having a “conal double” peak in its profile. Our observation picks this out very well.
The PRESTO analysis program results are shown below.
The conal double plot is produced from the raw data and plotted in excel.
PSR B1133+16 is located at RA 11h 33m 27s Declination +16.07°, in the northeast part of the constellation Leo. It was observed with a pulse period of 1.187 seconds. Our center frequency was 417 MHz, and we used a 10 MHz bandwidth.
(The name B1133+16 conveys the celestial sky coordinates, referenced to a standard year epoch. In this case the B indicates the position is from the year 1950, the “Besselian” year, named after the German astronomer Friedrich Bessel.)
Congratulations to the entire membership for turning the DSES dish into a world class scientific instrument!
Thanks!
