| SCIENCE_2 | Passive Radar Acquisition mode with 10% DC mode.
Telemetries from the NECP operation in SCIENCE_2 mode and found that the total power of RIME is 11.6W (divided in RDS: 8.87W and Tx: 2.74W). Some minor variations are visible during the instrument operation, up to 20mW. Probably in the future we may be able to model them but I think that their effect is negligible. | RIME |

| SCIENCE_05 | Flyby Aquisition mode with 5% DC mode.
RIME observations during flyby with variable instrument parameters, high vertical resolution and deep penetration.
Since during flybys the instrument parameters (i.e. pulse repetition frequency) varies to adapt to the altitude and speed changes, both datarate and power consumption are not constant for the entire acquisition duration. Datarate max and min bound profiles could be computed analysing the instantaneous altitude and velocity w.r.t. the moon surface. Shielding from Jupiter noise is advisable but due to the sporadic nature of Jupiter noise RIME should be operated in the unshielded areas too. To be noted that during Europa Flybys the Jupiter noise shadow cone boundary is often very close to the trajectory around closest approach, thus very small variations of altitude and latitude of the CA can result in huge variations of the full Jupiter noise shadow duration.
The datarate strongly depends on the altitude uncertainty a priori knowledge. | RIME |
