STEREO-B SWAVES One minute averages of the high (hfr) frequency receiver data.

ResourceID
spase://NASA/NumericalData/STEREO-B/SWAVES/average_hfr/PT60S

Description

The two STEREO radio receivers measure wave intensity, source direction and angular size in the frequency
range 40 kHz to 16 MHz, corresponding to heliocentric source distances of about 1 Rs to 1 AU. One 10-40 kHz
receiver measures radio and plasma waves near the 1 AU electron plasma frequency. One receiver makes high
time resolution measurements at 50 MHz. Time Domain Samplers make simultaneous wideband waveform measurements
on three electric components. Antenna systems include three mutually orthogonal 6-meter monopoles.
