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, as for example when `PRECISE <precise.html>`__ 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.
