Photometric IRAC and MIPS points for Yggdrasil, Thor, and Loke after de-blending.

Instrument Wavelength SYggdrasil SThor SLoke

IRAC 1 3.6 21.9 9.02 <2.10
IRAC 2 4.5 36.1 21.0 <1.32
IRAC 3 5.8
IRAC 4 8.0 30.2 < 21.4
MIPS 24 468 ± 40 180 ± 40

Notes. Thor is not detected in the IRAC 3 image, however the flux at the position is influenced by an image artefact from a nearby star in the field. Extracting even an upper limit at this position is therefore not possible. Loke is not detected in any of the IRAC images; we quote the 3σ upper limits (Wylezalek et al. 2013).
