Prototype DFB - testing and usage

Diary

20/06/05: prototype installed at Parkes by Grant, Andrew and Warwick
21/06/05: initial testing of the prototype DFB (Grant, Andrew, Warwick, George)

First observation: PSR B0628-28

PSR B0628-28 was subsequently observed with various configurations. We recorded using 2048x2048 channels/bins and seemed to record data successfully (according to spd). However, these files don't seem to record correctly using pav?

PSR J0437-4715 (512 channels/512 bins)

1 hour integration on PSR J0613-0200:

Vela at 10cm

PSR J0835-4510 with 2048x2048 channels at 10cm. The plot on spd seemed okay and so we probably have a problem with the FITS file.

PSR J0835-4510 with 1024x2048 at 10cm.

Vela at 20cm

PSR J0835-4510 with 1024x2048 at 20cm.

PSR J1022+1001

PSR J1022+1001 at 20cm.

Usage

Wiring

Creating a schedule

Schedules are produced using the same format as for the wide-band correlator (WBCORR). In brief:

  log on to e.g. pavo using the pulsar account
  >cd /psr1/wbcorr

Select suitable configuration files for each pulsar. The table provides the maximum pulsar spin-period (in milliseconds) for every possible combination of number of channels and phase bins. The number in parentheses is the value for only 2-channel output (instead of the standard 4 channel).

DFB channels			Phase bins
	256	512	1024	2048
128	0.8(0.5)	1.5(1.0)	3.1(2.0)	6.2(4.0)
512	2.6(1.5)	5.2(3.0)	10.4(6.1)	20.8(12.3)
2048	10.4(6.3)	20.8(12.5)	41.6(25.0)	83.0(50.0)
