Wide‐Field Millimagnitude Photometry with the HAT: A Tool for Extrasolar Planet Detection
Wide‐Field Millimagnitude Photometry with the HAT: A Tool for Extrasolar Planet Detection
We discuss the system requirements for obtaining millimagnitude photometric precision over a wide field using small aperture short focal length telescope systems, such as are being developed by a number of research groups to search for transiting extra-solar planets. We describe the Hungarian-made Automated Telescope (HAT) system which attempts to …
