current title is former title was How error bars on recent speed of gravity determination from gravitational waves and coincident gamma ray burst? Was Hubble constant in there? and it is explained in this comment
Thank you for point that out! I remember struggling this morning trying to get the title to be under 150 characters as required by SE, and it looks like after several edits it's become unparsable. If I had 240 characters the title would be more like
For the recent determination of the speed of gravity based on the timing between the detection of gravitational waves and nearly-coincident gamma ray bursts, how were the error bars determined? Was the Hubble constant used as part of this?
If you can think of a better title please feel free to edit. Otherwise I'll have a look tomorrow.
Can someone propose a title that captures enough of the key words to be specific, searchable and "attractive" in the sense that it encourages those interested in the topic to see what the answers say, but isn't overly lengthy?
