Resources like the
AAVSO International Variable Star Index (VSX) describe the many categories of variables (periodic and aperiodic). Many groups can be further divided into subgroups. For example, a Delta Cepheid is a kind of pulsational variable, which can be further subdivided into the groups:
DCEPS and DCEPS(B). I recommend referring to these resources to build your understanding of the many types of variable stars.

Creating the Light Curves
This is actually a separate post. As soon as my account is upgraded this content will move to a separate document. This describes the generation of the image-subtracted, trend-filtered, light curves from start to finish.
1. Determine the channel and quarters that you will need for your cluster of choice
- This is slightly trickier than it sounds. The Stellar Cluster Project" is a special component of the Science Program. Data can be identified on the Kepler Data Search and Retrieval page, using the investigation ID = STC, as shown in the figure below. We will use long cadence data only.
- Sort and compare the RA/DEC listed in the data to that of your chosen cluster. Write down the Sky Group ID (this should not change with quarter or channel). Also write down the channel corresponding to each of the quarters.
