urn:nasa:pds:vg2-pra-nep:data-lowband-6sec:vg2-nep-pra-6sec 1.0 1.25.0.0 Product_Observational 1991 This product contains high time resolution and low rate receiver band 6 second sweep data from the Radio Astronomy instrument on Voyager 2 from the Neptune encounter. The data are provided for 70 low band channels ranging from 1326.0 to 1.2 kHz and spaced 19.2 kHz apart. Columns SWEEP1 through SWEEP8 each contains 71 fields corresponding to one status word and 70 channel data.

In each sweep, the first data value in low band (1326.0 kHz) occurs some 3.9 seconds after this time. Subsequent data points are sampled at a lower frequency interval of 0.03 second. Only one time is given for the entire major frame, thus the start time of each sweep in the major frame is given by this time plus 6 times the sweep number minus 1 (i.e. 0 through 7). 71 1 0 13 284 SWEEP1 1 1 ASCII_Integer 4 mB 71 4-byte integer data values.
