An Example Dataset
To start your investigation, we suggest you measure the brightness of as many stars as possible from a test dataset taken by Faulkes Telescope (FT) North of the open cluster, NGC 957. The two FITS files required are available for download from the FT Project's website. A finder chart for this open cluster is also available from this page.
Once you have created your CMD, you may wish to compare it with our version (see Figure 1). If your plot looks like Figure 1, you can be confident to proceed with some other datasets. Once you are happy that you can produce a plot which is similar to that above, you can continue and analyse some additional datasets.
