I noticed the same using "Replay". Then I realized that the Replay
Y-Scale and digital filter parameters were either the default or I had
set them the last time replay was used.
Also this is channel dependent. Channel one Replay will have a different
setup then channel two Replay.
Using the "Start" button or the "Update" button after doing a Replay run
will only affect the items in there respective fields.
I have been using Replay a lot to go back and see what I was missing
because I didn't know what I was doing the first time.
Doing a replay of 24 hours of data with the low pass at 0.1 Hz, high
pass set to 0.016 Hz and Y-Scale =1 is quite interesting with the last
several days of teleseismic events we have been experiencing.
Larry, Thanks for the Replay UTC 00:00 hour event spanning advice. Works
great.
