The sources box for Type IA supernovae was added. These sources are distinct from the higher frequency core collapse supernovae which were already plotted. The amplitude of box plotted here corresponds to an optimally orientated type IA supernovae at 30 kpc (i.e. in the Milky Way). The event rate for type IA supernovae in this volume is low; a rate of the order 1 in 100 years.

For details on type IA supernovae as sources of gravitational waves see this paper (arXiv:1511.02542).

The aLIGO sensitivity curve was updated. We now plot two sensitivity curves, one for the sensitivity during the O1 run (commenced September 2015) and one for design sensitivity. Therefore the curves plotted here no longer matches that in the companion paper.

Details of the O1 sensitivity may be found in this paper, it is the curve labelled "early", the data is available here.

Details of the design sensitivity may be found in this paper (arXiv:1411.4547), it is the curve labelled "zero detuning high power", the data is available here.


We thank colleagues from the LIGO Scientific Collaboration including Chris Messenger and Rana Adhikari for useful comments and pointers to updated information.

We would also like to thank Ivo Seitenzahl for a useful discussion concerning type IA supernovae as gravitational wave sources.
