    This course will use the second half of the AAVSO Guide to CCD Photometry and will cover topics including optimal image photometry settings and techniques, transformation, and basic error estimation. We'll also discuss how to plan an observing run to optimize the scientific return of your observations. Part I of this course is not a prerequisite, but is very strongly encouraged for new CCD photometrists. Image processing software is required, but images will be provided for those without their own equipment.

    This course is intended to provide participants with a systematic coverage of VStar's current functionality, an appreciation of the ways in which it can be extended, and how it can be used for variable star data visualization and analysis.

    You’ll learn how to create mean plots, phase plots, and perform simple period analysis. This is not a course on statistics, but relevant statistical concepts as they apply to the use of VStar will be introduced through reading and discussion.

    You must successfully complete exercises and weekly quizzes as well as a final examination to pass the course.

    VStar is written in the Java programming language, requiring at least version 1.7 to run on Windows, Mac OS X, Linux, and OpenSolaris.

    This course will cover the techniques necessary for observers to produce highly accurate variable star observations using single channel photometric photometry (PEP). We will cover the history of PEP technology and its continuing relevance today, as it fills a gap left by CCD and large automated surveys for precision photometry of bright stars.

    Equipment and observing techniques will be presented as well as detailed discussions of data reduction and error source identification and correction. Spreadsheet based tools for extinction, transformation, and data reduction to the standard system will be provided for use in labs using sample observation sets. Specific techniques applicable to commercially available single channel photometers, such as the Optec SSP-3 and SSP-5 will be covered in detail.

    The course will use the newly created Photoelectric Photometry Observing Manual as its primary text, but will augment this material with additional readings and tools available on the AAVSO website.

    You must successfully complete exercises and weekly quizzes as well as a final examination to pass the course.

    This course is intended for VStar users who have taken and passed the basic CHOICE VStar Course, How to Use VStar. This course assumes that you already know the mechanics of using VStar. The objectives of this course are to provide participants with a better understanding of analysing data with VStar, what you are doing when you use VStar and why it works. That means the course explores basics of underlying theory, limitations of the analysis and valid conclusions one can draw from the results and conclusions that one cannot draw from the results. The course will also afford ample practice in applying the various analytical tools VStar provides.

    This will be achieved by guided reading, exercises (both illustrative and real-world), forum discussions, quizzes, and a final exam or project. The text for the course is Analyzing Light Curves: A Practical Guide, by Grant Foster, which will be applied to the use of VStar. The book is available from Lulu.com and is required for the course (Please order your book at least 2 weeks before the start of the course.)
