"Chart ID" or "Sequence ID" of the photometric table?

Announcement: New Forums

We are excited to announce the launch of our new forums! You can access it forums.aavso.org. For questions, please see our blog post. The forums at aavso.org/forum have become read-only.

You report the chartID that you see on the photometry page. 

But note that with the new VSP API, this chartID will be the same as that of its related finding chart!

This is change from the old VSP and one of the improvements from Will's efforts at HQ.

There is a strange behavior.
In VSP, if I plot a chart for a variabile, and then click on link "Photometric table for this chart", the two sequences differ for last letter.
Instead, if I put the Chart ID and plot the chart, and then click on link "Photometric table for this chart", the two sequences are the same.

Yes, you might get different chartID's from the chart page and the photometry page. But they will be equivalent. Either yield the same photometry when put into the system which uses the API.

Try plugging both chartID's into the api:

https://www.aavso.org/apps/vsp/api/chart/put-chart-id-here/?format=xml

The will return the same information. They better!

So, for the purposes of building AAVSO Extended Format records for WebObs, you can use either.

Thank you very much, George.
