1. Wqed: A new tool for Abstract: We present a set of tools for processing time-series photometry. Observations of variable stars typically need to be corrected for atmospheric effects - clouds and other transparency variations - before being analysed with tools such as Period04. The Whole Earth Telescope developed a new package for this task that was successfully used in our spring campaign. Wqed contains a graphical interface for lightcurve division, smoothing, bad point removal, and other common tasks. It also provides a script for extracting header information from fits files. A modular design and ASCII formats simplifies the adaptation of Wqed to a new telescope or reduction pipeline, and has been successfully used on all 25 telescopes that participated in XCov26. We have found these tools useful and easy to use, and make them available to the general community. Fergal Mullally Dept. Astrophysical Sciences, Princeton ( fergal@astro.princeton.edu)

3. Target White Dwarf Lightcurve Up to 8 Reference stars Sky counts Status Bar Select a region and zoom in using your mouse

4. Use your mouse to remove data badly contaminated by cloud. Text box gives instructions on what to do next. Don’t like what you did? Use the undo function.

5. Divide lightcurve by a combination of reference stars Fit trends, bridge gaps, and smooth data, all using the mouse and simple single character keyboard commands Mostly bug free!
