Abstract

(Abstract only) AAVSO made available, through the great volunteer work of Gordon Myers and George Silvis, two very useful tools, Transform Generator and Transform Applier (tg and ta) for transforming instrumental magnitudes to the standard system. I will juxtapose the steps necessary to obtain transformation parameters “the old fashion way” and how can the same result be achieved with these two tools. I will present transformation parameters for the Eastern Kentucky University (EKU) telescope obtained with the standard field M67. These parameters were applied to photometric results for AE UMa, a short-period, high-amplitude δ Scuti star (Period ~ 0.086 d).
