The goal of the Heliospheric Cataloguing, Analysis and Techniques Service (HELCATS) is to add value to the
STEREO dataset by cataloguing the properties of coronal mass ejections and corotating interaction regions observed
by STEREO. As part of this work, the complementary nature of radio measurements and white light observations
has been assessed. Here we report on the cataloguing of slowly-drifting radio emission observed by
STEREO WAVES in conjunction with events identified in the HELCATS manually-generated coronal mass ejection
catalogue. We present preliminary statistical results derived from the catalogue, in particular the extent to
which radio emission is more likely to occur in conjunction with fast coronal mass ejections. We further use the
catalogue to make an initial assessment of the angular deviation between radio emission and coronal mass ejection
motion, in order to determine which part of the coronal mass ejection contributes most to the radio emission.
