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.
