Transforms: Everything you need to transform your CCD observations

This page serves as a central location for the tools AAVSO voulnteers are developing and promulgating to help fellow photometrists transform their observations, making them compatible and more useful to the professional astronomy community.

These include:

  • Transform Generator (TG) - A tool to compute the transform coefficients. Details of this program can be viewed at: TG is a Python application that will run in Windows, Mac, Ubuntu and Linux environments. Author: Gordon Myers.

Photometry Transformation Generation Program

The Photometry Transformation Generation Program (PTGP) has been renamed to Transform Generator (TG) and is now located here:



Welcome to the TransformApplier (TA), a tool prepared for the AAVSO by "super-volunteer" George Silvis (SGEO), to make it easy to submit transformed CCD observations to WebObs. We, members of the AAVSO, want to submit transformed observations because these can then be used more easily by professional astronomers. We're amateurs, but sophistocated amateurs, and this tool will help us go the next step.
