I got mail about this from Jon W. Meyer, an artillery type who can't post
from his machine:

    Sorry, Henry, but "low angle fire" for artillery has a particular
    definition.  Essentially, any tube elevation less than or equal
    to 1600 mils or 45 degrees is "low angle".  Anything above this
    is "high angle".  Actually, the firing tables for most indirect
    fire weapons don't provide data within two hundred or so mils of
    1600 becase the CEP becomes unacceptably large.  (This is more
    true when firing with larger propellant charges than with smaller
    ones).
