Back in October, I announced that the Bright Star Monitor EPD was available, giving you access to 66 million datasets from those 5 telescopes. As I've mentioned before, all images taken by AAVSOnet telescopes are archived at headquarters, and all stars in every frame are extracted and measured with an automatic pipeline, in addition to being sent by request to researchers.
We've now gone back and created epoch photometry databases for two telescopes that are no longer part of the network. Wright 28 (W28) was one of the first AAVSOnet telescopes, and ran for several years in New Mexico. Krajci 35 (K35) was only operational for one year at Astrokolkhoz Observatory, but was very active during that year. These two telescopes add about 8 million records to the master EPD, primarily of a few hundred deeper fields. Many of those entail time series observations in a single filter, or are monitoring observations of CVs.
We've added those two new datasets to the master database, which is described at
https://www.aavso.org/aavsonet-epoch-photometry-database
Members can search the entire database from
https://www.aavso.org/search-aavsonet-epoch-photometry-database
or by using VStar and its latest EPD plug-in. You are welcome to search these new additions to discover new variables or obtain measures of known variables. Remember the ground-rules, though: the AAVSOnet EPD is a separate product from the AID. You cannot take the measures you extract from the EPD and submit them directly to the AID using WebObs. The preferred use is for your own research, as supporting photometry. I think the AAVSO is going to display photometry from the EPD from a new light curve generator, and as mentioned earlier, VStar already can do this. If you must submit EPD photometry into the AID, we ask that you give value-added processing: differential photometry using nearby comparison stars, culling of bad nights or poor images, etc. Be aware that many of the images may have been part of a research project, and their photometry may already be in the AID, so carefully double-check before making any submissions that you are not duplicating effort. Include a comment line indicating that the photometry came from the AAVSOnet EPD.
The next EPD to be released will be SRO35, which was part of the network for about 6 years before being replaced by SRO50.
Enjoy!
