EA spreadsheet available

We recently released a significant update to the backend systems for the AAVSO website. While most of the bugs introduced by this update have been fixed, there may still be problems we haven't fixed. If you run into a problem, please email webmaster@aavso.org

As promised, the spreadsheet of EA stars in low galactic latitudes is available. There are two worksheets - one containing all 2495 stars and the other derived from a macro I penned which only lists those stars with amplitudes above 0.9m.

Next step will be to make that smaller sample even smaller by removing those stars which are definitely EA, leaving a 'hot list' of dubious, or little-studied, objects. Just an idea though!

The spreadsheet is Excel 97, which I know is practically antediluvian now, but I assume that later versions can open it.

John Greaves has put the stars in the spreadsheet through various filtration methods and it appears that there is 1 likely candidate and 2 less likely ones (based on infrared excess). All of them are faint, and may be better suited to CCD observation.

The likely one is MN Ser, and the less-likely ones CK and GV Mon. John's list does not include stars South of -20°. Maybe a look among those stars using perhaps ASAS would be an idea.
