This collection supplements: Wu et al. (2023), Rotational Modulation of the High Frequency Limit of Saturn Kilometric Radiation. J. Geophys. Res., Volume 128, Issue 4, article id. e2023JA031287. doi:10.1029/2023JA03128.
Raw text files
The collection is composed of three text files containing the northern and southern High Frequency Limit (HFL) for the Saturn kilometric radiation (SKR) as observed in Cassini/RPWS/HFR data:
Reading the raw data
Python code to load the data:
from astropy.time import Time
from astropy.units import Unit
import numpy
with open("SKRHFLderived_time_Format_t1997_v0830.txt", 'r') as f:
t = f.readline()
t = numpy.array(t.split(), dtype=float)
t = Time('1997-01-01') + (t - 1) * Unit('d')
print(f'Time range: {t[0].iso} to {t[-1].iso}')
with open("SKRHFLderived_HFL_N_v0830.txt", 'r') as f:
n = f.readline()
n = numpy.array(n.split(), dtype=float) * Unit('kHz')
with open("SKRHFLderived_HFL_S_v0830.txt", 'r') as f:
s = f.readline()
s = numpy.array(s.split(), dtype=float) * Unit('kHz')Time range : 2004-01-01 to 2017-09-15
Spectral range : 98.9 kHz to 1.29 MHz
Location: Saturn
