Pulsar Data analysis Desh, Anish RRI

This report presents preliminary results from pulsar data analysis conducted on B0834+06 and B0950+08 during the MWA meeting in Canberra, held from January 19-23, 2009. Data was obtained on November 18, 2008, in transit mode, covering a bandwidth of approximately 1.2 MHz over ~600 seconds for each pulsar. The analysis includes incoherent addition results, with ongoing work in coherent dedispersion mode. Key parameters such as dispersion measure, rotation frequency, mean flux density, and pulse widths have been calculated for both pulsars.
