When RELSCF=n is present, the default SCF criterion is multiplied
by n. This is useful if the value of the default SCF criterion is not
readily available, as for example when PRECISE or any
other keywords that modify the SCF criterion is used. Examples: RELSCF=10 will make the SCF test
easier to pass--the criterion will be made 10 times easier. Similarly,
if the results are not precise enough, then RELSCF=0.1 would
increase the precision 10 times. However, if the precision is increased
too much, the SCF test might never be passed. See also SCFCRT.
