It would be mis-interpreted as a violation signal because, like it, it is not detected by the accelerometer made of test bodies of equal composition (density) used for checking of systemtics

EP tests in LEO: the most subtle disturbance (I)

Radiometer effect: residual gas pressure p and temperature gradient dT/ds (due to exposure of the s/c to a radiation source) cause an acceleration on the test body of density r (different for bodies of different composition):

In LEO, exposure to infrared radiation from the Earth causes a differential radiometer effect with the same signature as an EP violation signal
