Voyager: gpuspec command line vs. .fil file output
siemion opened this issue · comments
For the Voyager tutorial, the gpuspec command line does not appear to be the one used to create the output filter bank file. The output filter bank file has a very large integration time, and is different than any other (known) BL data products.
Can someone please comment on how this came about, and perhaps add some explanatory text in the tutorial?
Looking at the name of the file:
voyager_f1032192_t300_v2.fil
I'm going to guess that it was run with
-t 300
rather than
-t 15
as suggested in the tutorial
Which would seem to match:
1/(1500 MHz / 8 / 64) * 1032192 * 300 == 105.696s
(300 spectra, each made up of 1032192 data points from one of our 512 polyphase channels)
