The output
tcsh: -nobout: Command not found
indicates that you might have a blank after the closing '\' of the previous line in the script, since it looks like the script is trying to run a program of the name '-nobout', which doesn't exist. The '\' characters should be the last ones on their lines -- if they are followed by a blank, they effectively become meaningless, and do NOT act as a line continuation marker.
As for the specific question:
Whether you have to censor out times with large movements -- no one can answer that for you. You will have to try it both ways and see if you get any significant difference.
