Photometry python
WebDifferential Photometry is comparing the difference between a target star and a comparison star. This is most useful in Time Series observations.. The direct comparison of a target and comparison star in the same field of view eliminates all other observational variables leaving a direct, differential comparison. Example: light pollution.
