Apparent and absolute magnitudes of GJ 436 and its planet.

Wavelength Magnitudes
(μm) Star Planet
Apparent Absolute Apparent Absolute

3.6 5.88 5.85 15.26 15.23
4.5 5.84 5.81
5.8 6.28 6.25 15.38 15.35
8.0 6.27 6.24 14.87 14.84

Notes. We estimate the errors of the apparent and absolute magnitude around 0.07 mag and 0.12 mag respectively, taking the uncertainty into account in the absolute calibration, the photometric error, the uncertainty of the zero magnitude flux, and the error on the parallax.
