[Aavso-photometry] CCD Observations of Epsilon Aurigae

[David Daiku Trowbridge]

I've posted a document describing how I have used a 4" telescope with a
3-hole mask to do BVRI photometry of Epsilon Aurigae. Also, I've included
examples of Excel spreadsheets that I've used to determine standard
magnitudes following the methods of Bruce Gary and Priscilla Benson.
Standard magnitudes for the comparison star Lambda Aurigae are from Jeff
Hopkins. Transmission coefficients were measured using M67.
