Use of "issue" in error message
When checking for calibration envelopes for an event, if the files are missing, the error message refers to "this issue". I don't think it's clear what is meant by "issue" in this context. Does this mean event?
Example
(Run on LHO)
$ asimov event calibration GW150914_095045
GW150914_095045
Traceback (most recent call last):
