Update GCN notice types to reflect additional facilities
There are two places in our GCN Notices that are specific to the present set of gravitational-wave facilities and collaborations:
- The IVORN, which starts with the string
ivo://gwnet/LVC
. - The
<contactName>
element in the<Who>
section, which contains the textLIGO Scientific Collaboration and Virgo Collaboration
.
We need to update this to reflect additional facilities (KAGRA and eventually LIGO-India) or simply make it completely generic and future-proof.
