adresses #107

If this is good should I go ahead and update the CHANGELOG in this PR as well to reflect the changes we are going to put into 4.0.2?

[nick-falco]

Yeah update the change log. I assigned milestones to all the issues resolved in v4.0.2. It's a good idea to reference the issue number for each item.

I'll test this now.

The receiver-id shows up at the station level in the StationXML output. I thought receiver-id was the same as the das? Wouldn't this mean that it should be at the channel level?

[nick-falco]

@derick-hess Oops I notices a few small typos "teh" instead of "the" and "atribute" instead of "attribute"

[derick-hess]

I'll fix that

[derick-hess]

Yeah I think channel level might be the more correct place to put that since there are cases you might have multiple receivers at the same station. I'll update the change log and move it to the channel level now

[nick-falco]

Yeah I think so assuming I'm understanding its meaning correctly. Like you said, there may be cases where you would have 3 single component instruments.

[derick-hess]

We do that sometimes with texans where 3 single channel texans are attached to one 3 channel sensor, so having receiver-id at channel level is correct.

Looks good. Go ahead and squash merge if you're happy with it.
