Specifying individual data channel (channel.N) parameters:
Each channel is specified by:
FileURL[#groupIndex[#inclination[#azimuth]]][[#<parameter>%<value>]...]
where FileURL is the path and filename or the Internet Uniform Resource Locator (i.e. http://<host>/<filename>) for a data channel, groupIndex (0, 1, ...) is the index of the trace-group to contain the channel, inclination (0-180 deg from vertical up) and azimuth (0 to 360 deg from North) specify the orientation of the channel and will override any orientation specified in the data file.
<parameter> is "group", "inclination", "azimuth", "multiplier", "format", "binarytype", "response", or "source" or the first 2 letters of one of these names; <value> is the corresponing numeric or string value.
If format, byte order or response file are not given in the individual channel specification, the corresponding values specified by the program parameters "channel.binarytype", "channel.format" and "channel.response" will be used.
If a group index is not given in the individual channel specification, the grouping of channels is controlled by the program parameter "channel.groupmode":
ALL - all channels are placed in a single trace-group
SINGLE - each channels is placed in a new trace-group
AUTO,<nchar> - all channels whose FileURL's differ by up to <nchar> characters are placed in a new trace-group
"source" specifies the initial source time/dist for TauP/Phases display for this trace (see "taup.source" for format)
Data files that have been compressed with gzip can be read directly by SeisGram2K, these files must have names ending in ".gz".
When SeisGram2K stand-alone is invoked from the command line, data channel arguments can be specified without the "-channelN=" prefix, and may include wild-card characters "*" and "?".
