RELSCF
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. 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.
