| 10 | + <Description>There are two estimates of the photoemission current from LAP1 sweeps of a sunlit probe. | |
| 11 | +I_PH0 in PHO files is a statistical estimate from several sweeps (over 60 minute | |
| 12 | +windows), while I_PHO in the ASW files is an estimate from a single sweep with larger | |
| 13 | +uncertainties but higher time resolution (usually 160 s). As LAP1 has shown no significant | |
| 14 | +contamination effects, these estimates should be directly proportional to the EUV flux at the | |
| 15 | +Rosetta position in the 20-130 nm band [Johansson et al, 2017]. For LAP2, the same | |
| 16 | +techniques have revealed a lower photoemission at the start of the cometary phase of the | |
| 17 | +emission, and a sharp drop in photoemission after significant thruster firings (e.g. dayside | |
| 18 | +excursion, 60% decrease) with sporadic recoveries and relapses. We therefore only use LAP1 | |
| 19 | +based values. | |
| 20 | + | |
| 21 | +While there is no other source of photoemission measurements than LAP, its value is | |
| 22 | +controlled by solar EUV radiation which is known from e.g. TIMED and SDO at Earth and | |
| 23 | +MAVEN at Mars. Photoemission values by both methods were presented by Johansson et al. | |
| 24 | +[2017] and compared to Earth and Mars data. The two methods were found to give consistent | |
| 25 | +results, also in agreement with a third independent method immune to instrument offsets. | |
| 26 | +However, around perihelion all methods returned about 50% less photoemission than | |
| 27 | +expected from the Earth and Mars EUV fluxes. This may be a real effect, for example because | |
| 28 | +of attenuation of solar EUV radiation by large numbers of small dust grains at large distance | |
| 29 | +from the nucleus. It is also possible that this somehow relates to probe surface contamination, | |
| 30 | +though no other such effects have been noted on LAP1</Description> | |
