Abstract

We present a new observing mode using WirCam on the Canada-France-Hawaii Telescope (CFHT). The staring mode with WIRCam can observe a target for several hours on the same pixels of the array. This allows for characterization of the photometric variations of the target to less than 0.02%, or to a signal-to-Noise Ratio ≥ 5000. The technical challenges encountered to implement this mode are described as well as a simple model to estimate the idealized performance of this observing mode. Early results are also presented and compared to the models.
