For example, some stars put out large amounts of energy in the infrared part of the spectrum, so that this can produce a different relative magnitude rating than using light energy from the middle of the spectrum.

If the assumptions used in calculating energy are changed, then this seriously affects the final result, even though the same body of data might be used.
If one introduces the concept of energy of an earthquake then that is a theoretically derived quantity.
