GET API access to Variable Star Database May 4, 2012 - 1:58pm

The Variable Star Database (VSD) is the collection of comparison stars plotted with our Variable Star Plotter (VSP). We have created an API for the public to query the VSD and get back photometry on those comparison stars. This is basically the same data shown in the "photometry table" option of VSP, except it is in a delimited format easily parsed by automated software. In other words, you can use this format for your own scripts/software/etc.
