This dataset consists of edited browse data derived from anoriginal dataset obtained from the Voyager 2 Planetary RadioAstronomy (PRA) instrument in thevicinity of Uranus. Data are provided for 70 instrumentchannels covering the range from 1.2 kHz to 1326 kHz inuniform 19.2 kHz steps, each 1 kHz wide. Data are includedfor the period 1986:019:00:00 through 1986:031:23:59. In orderto produce this dataset from the original raw PRA data,several steps have been taken:1. The PRA operates in a variety of modes; data from modesin which the receiver does not scan rapidly through itsfrequency range have been removed;2. The data have been calibrated as best we know how;3. The data have been split into Left Hand Circular (LHC) and Right Hand Circular (RHC) components;4. The data have been binned into 48-second intervals.Thus, values at a given channel are separated in time by anincrement of 48 seconds; each 48-second time interval hasassociated with it a value for LHC polarization and one forRHC polarization.During data gaps, the entire record is absent from thedataset; that is, missing records have not been zero-filledor otherwise marked. Bad data within a record is indicatedby the value zero, which cannot otherwise occur.Each datum is returned as a 16-bit quantity; it representsthe mean power received in the given channel at thespecified time and polarization. The returned quantity isthe value in milliBels (mB) about a reference flux density. The value of0 mB represents a voltage of 1 microvolt across the frontend of the receiver. To convert a returned quantity to flux,use the formula: flux : 7.0x10^(-22)x10^(Mb/1000) W m-2 Hz-1

This dataset includes all the available low-rate scanningmode data for the frequency range below 1326 Khz for thetime interval covered. Known bad data have been set to zero.Data which appear to exceed the Full Scale Deflection (FSD)of the instrument (i.e.the most intense signal which can be measured reliably) havealso been set to a zero (should they occur). Planetary RadioAstronomy (PRA) suffersfrom interference from many other instruments aboard thespacecraft. No attempt had been made to remove theseinterferences in this dataset. The two most obvious examplesof this interference are low-frequency spikes which occurevery twelve minutes throughout the dataset (due to LECPoperation), and a strong, wandering interference (from PPS)that occurs in the range 200 to 600 kHz at various timesthroughout the encounter. An example of the latter is to befound at 1986-01-24 09:00:00 SCET.The separation into Left Hand Circular (LHC) and Right HandCircular (RHC) polarization components isperformed on the basis of the polarization of the incomingwave as perceived by the instrument. This takes into accountneither the antenna transfer function nor the spacecraftorientation with respect to the source. In general, themapping of perceived polarization back to emittedpolarization cannot be solved without a knowledge of bothof these factors, as well as a knowledge of the type ofpolarization coming from the source region (e.g. is itlinear or circularly polarized?).Most planetary emissions are circularly polarized. Below isa table showing the response of the experiment to a lowfrequency (100 Khz) LHC wave. The response does not changemuch up to about 5 MHz. SAMPLING_PARAMETER_NAME : TIME SAMPLING_PARAMETER_RESOLUTION : 0.001 MINIMUM_SAMPLING_PARAMETER : N/A MAXIMUM_SAMPLING_PARAMETER : N/A SAMPLING_PARAMETER_INTERVAL : 48.0 MINIMUM_AVAILABLE_SAMPLING_INT : 12.0 SAMPLING_PARAMETER_UNIT : SECOND DATA_SET_PARAMETER_NAME : RADIO WAVE SPECTRUM NOISE_LEVEL : 2400 DATA_SET_PARAMETER_UNIT : MILLIBELThe coordinate system used is: THETA : 0 is along the MAGboom; PHI : 0 is the bisector of the two PRA antennas. Thethird column is the apparent value of the left handcomponent as perceived by the receiver. That is, a value of+1.0 indicates that the incoming LHC wave is correctlydetected as a pure LHC wave. A value of -1.0 will bedetected as being of the correct strength, but incorrectpolarity. A value of, say, 0.6 indicates that the totalenergy is split 60% into the apparent LHC component and 40%into the apparent RHC component. The table below has beenproduced using a wire-frame model of the spacecraftcomprising 168 separate elements, and derived using themethod of moments procedure. IT IS ONLY A MODEL, not ameasurement; but appears to be very accurate for the lowband of the PRA instrument.
