The 2017-04-28-10:03:02_01.fil i download from https://data.csiro.au/collection/csiro:34437v3 This file is in cutouts/FRB1704. Then i run with heimdall generate 2017-04-28-10:03:02_01.cand file.
The parameters in the file is below:
14.869 10956 13.8754 10 68 225.311 2817 8046 11714
Then i use the your tutorial https://thepetabyteproject.github.io/your/ipynb/Candidate/ with the parameters below:
cand = Candidate(
fp=fil_file,
dm=225.311,
tcand=13.8754,
width=3,
snr=14.869,
device=0,
)
And generate dispersed frequency-time, DM-Time and dedispersed frequency-time images like this:

Is there something wrong with my operation. I can't find the characteristics of a fast radio burst.
