The catalog contains dynamic radio spectra associated with solar energetic particle (SEP) events in solar cycle 23 (1997-2006). Each plot is a frequency-time representation of the observed radio emission where the intensity is given in color code. The majority of the used quick-look spectrograph plots are available on-line from the ground-based radio observatories (given below in alphabetical order):

ARTEMIS (20-650 MHz): web.cc.uoa.gr/~artemis/Artemis4_list.html
Culgoora (18-1800 MHz) and Learmonth (25-180 MHz): www.ips.gov.au/World_Data_Centre/1/9
DAM (20-75 MHz): bass2000.obspm.fr/home.php
Green Bank (18-70, 170-1070 MHz): www.astro.umd.edu/~white/gb/index.shtml
HiRAS (25-2500 MHz): sunbase.nict.go.jp/solar/denpa/index.html
Izmiran (25-270 MHz): www.izmiran.ru/stp/lars/
Ondrejov (800-4500 MHz): www.asu.cas.cz/~radio/info.htm
Phoenix-2 (100-4000 MHz): soleil.i4ds.ch/solarradio/

The data at decimetric (dm) and metric (m) wavelengths from the ground-based observatories is complemented by dekametric/hectometric to kilometric (DH/km) data from the Wind/WAVES satellite www-lep.gsfc.nasa.gov/waves/data_products.html.

A stacked plot for each SEP event is prepared, whenever radio spectra are found. The radio spectra are ordered top-to-bottom as dm (ranging from 4500 to 800 MHz), m (from 800 to 20 MHz) and DH/km (0.02-14 MHz) wavelengths. These spectral plots are given together with the GOES SXR light curves (always on the top of each spectral graph). Since we use quick-look data as provided by the different observatories, the color table of the final compound plot is not uniform. Because the purpose of this catalog is a qualitative evaluation of the radio signatures we keep the original plots. In addition, the utilized plotting routine did not specify a uniform color code for the Wind/WAVES data.
