[webservices] fdsnws-event service - New Release

[Chad Trabant]

Hi Philip,

That is correct.  We struggled with this one quite a bit and there is really no right answer.  The issue is that magtype can mean either what is searched on (as specified by the spec) but also specify what is returned.  If we change the logic to what you propose there will be no way to request only all magnitudes of a given type for events.  There are simply not enough parameters to separate these use cases unfortunately.  Understand that it remains quite easy to get all magnitudes without specifying any magtype for the server and doing more advanced selection downstream if needed.

It would be useful to hear from other users regarding what would be useful.  The 'magtype' parameter, per the specification, specifies which magnitudes should be used for matching the criteria (min and max).  Should the 'magtype' parameter also be interpreted as a selection of what to return?

thanks
Chad

Meaning if I query "magtype=MB&includeallmagnitudes=true" then I might get 5 magnitudes, but they will all be of type MB?

I think there is definite value in being able to get ALL magnitudes when searching on a particular type. Being able to get all magnitudes of a given type actually seems less useful to me. In most cases I am quit happy to get the "best" magnitude of a given type, but there are cases where I want to see the best Mb and the Mw and ML for the events I am interested in.
