## Revisions of and (JUL-2026)

The and values were revised from in-situ measurements (see figure ). The following changes were made:

- the single band in band 1 was changed from 35.0 K to 37.1 K constant values,
- the dual band in band 1 was changed from a decreasing linear function to a polynomial function of order 2,
- the in band 3 was changed from 0.90 constant value to a decreasing linear function.

The resulting changes in are shown in figures and .
