SED of a Galactic source, PCCS2143 G000.35–19.48 at RA = 287.56° and Dec = −37.15°. The lines and points of different colors mark different observing epochs, separated by 6 months. It is important to note the larger scatter of the noisier LFI measurements at 30, 44, and 70 GHz. With the possible exception of 44 GHz, there is no evidence for variability, as expected for a large source of this type.
