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.
