This attribute is an
alternative to the
MaxOrder attribute and gives the best resolution of the MOC
expressed as a number of arc-seconds. It can be set only when the
Moc is constructed -
an error is reported if any subsequent attempt is made to set or clear the value of
MaxRes. See attribute MaxOrder for more details.
A default value of zero will be returned for the MaxRes attribute prior to its value
(or the value of MaxOrder) being set.
