Catalog not subsetting magnitudes properly

[gthompson]

Hello Dr. Thompson,

My name is Marlon and I'm a MS Geophysics grad student at Boise State looking at an Alaska earthquake catalog.

I've installed GISMO and it's working great at helping me quantify the robustness at the earthquake catalog I am interested. However, I was wondering if there is a way of using GISMO to produce a map of b-values (map view, not just the standard G-R relationship), which I know the older matlab package ZMAP can do.

And I noticed that the cookbook way to only parse out a catalog by magnitude type isn't working
e.g. :
data = Catalog.retrieve('iris', 'starttime', '2014-01-01', 'endtime', '2015-12-30','magnitudeType', 'ml', 'maximumdepth', maxDepth ,'boxcoordinates', region1);

should just extract local magnitude ('ml') events, but all magnitude types are included in the catalog upon inspection afterwards. Is there a work around for this?

Thanks for entertaining my questions!

Cheers,

Marlon
