Pulsar DFB

PDFB4 as Spectrometer

The ATNF Pulsar DFB related stuff are in this page. Currently supported are the timing and search modes. The baseband mode is not operational due to a firmware issue and is being discussed with ATNF.

A detailed Manual of the DFB timing mode can be found here.

DSPSR/PSRCHIVE can be used to fold and dedisperse search mode data from the DFB. Here is a short recipe:

• Copy data to pulsar server.
• Fold: dspsr -N 2021 -k Effelsberg -L 10 Srch_file.fits

In the above, -L is to create 10-second sub-ints, -N is the name of pulsar, -k is TEMPO site information.

• Once this is done, add all 10-sec subints: psradd -f add.ar 2010*.ar
• Now plot and view:

   freq-phase plots: pav -GTp -d add.ar
   
   time-phase plots: pav -YFp add.ar
   
 * Examples are in pulsar server: pulsar@134.104.64.64:/data1/ramesh/2111
