The one is a problem of interpolation, the other a step towards the solution of an equation in finite differences.
If within the range5100-3700A, the constants are determined once for all, the formula seems capable of giving by interpolation results accurate to o 2 A, but as a rule the range to which the formula is applied will be much less with a corresponding gain in the accuracy of the results.
When attention was called to the interpolation in the 9th century it became one cause of the schism between East and West.
