Description

This is a simple transpose operation. In all previous steps, the photometry is extracted simultaneously for all sources in a given image or in a short series of images. In order to study each source’s individual variability, the measurements from all frames for that source must be collected together. This step simply performs that reorganization. For each catalogue source, all available measurements from the individual frames are collected in a file, possibly combined with earlier measurements from say a different but overlapping pointing of the telescope or with another instrumental set-up.
