In science:

The WASP0 instrument was developed as a proof-of-concept instrument similar to Vulcan (Borucki et al. 2001) to search for planetary transits, and as a precursor to SuperWASP (Street et al. 2003), a more advanced instrument that has recently been constructed on La Palma, Canary Islands.

The transit depths from Charbonneau et al. (2008), crucial to constrain the temperature profile and water abundance, turn out to be incorrect by more than 3 sigma, due to the complex Spitzer instrumental systematics (the “ramp effect” and “pixel phase effect” affecting high-accuracy flux measurements).

To account for instrumental systematics, the light curves were fitted using a Gaussian-process model whilst simultaneously fitting for the transit parameters.

This is better done by analysing data from a single instrument, preferably acquired during a single transit.
