Description
May 25 to September 27, 1989 data from the Voyager 2 Planetary Radio Astronomy instrument during its Neptune encounter. The dataset contains high-rate frames, each 48 seconds long, with a 28-octet header and 1,280,000 octets of data per file. It was produced by the National Aeronautics and Space Administration.
Use Cases
Analyzing temporal patterns of Neptune's radio emissions based on the high-rate time-series data.
Studying the spectral characteristics of planetary phenomena using the four frequency channels described in the header.
Correlating radio flux measurements with other Voyager 2 instrument data based on the precise spacecraft time stamps.
Investigating signal processing and data acquisition methods for deep-space radio instruments based on the described frame and line structure.
Strengths
Data covers a defined four-month encounter period from 1989-05-25 to 1989-09 27.
Each data file has a detailed 28-octet header specifying year, day, time, spacecraft, frequency channels, and bandwidth.
The data structure is explicitly documented, including the 48-second frame duration and 800-line logical division.
Limitations
Column-level documentation is absent; field semantics for the main data stream must be inferred after download.
Row count and total dataset size are unknown, which may limit suitability assessment.
