Table Footnotes

[1]Types: A = Array, B = Boolean, C = Char, DT = DateTime, F = Float, I = Integer, R = Real, S = String, U8 = Unsigned 8-bit integer
[2]String is passed as-is, e.g. “szsrecs=true&repo=realtime” for FDSN. String should not begin with an ampersand.
[3]Specify region [center_lat, center_lon, min_radius, max_radius, dep_min, dep_max], with lat, lon, and radius in decimal degrees (°) and depth in km with + = down. Depths are only used for earthquake searches.
[4]Specify region [lat_min, lat_max, lon_min, lon_max, dep_min, dep_max], with lat, lon in decimal degrees (°) and depth in km with + = down. Depths are only used for earthquake searches.
[5]Not used with IRISWS.
[6]-v=0 = quiet; 1 = verbose, 2 = debug; 3 = verbose debug
[7]If -w=true, a file name is automatically generated from the request parameters, in addition to parsing data to a SeisData structure. Files are created from the raw download even if data processing fails, in contrast to get_data(… wsac=true).
