VizieR Online Data Catalog: Cold Classical TNOs: LCs & rotational properties (Thirouin+, 2019)

Our two main facilities are the Magellan-Baade telescope and the Lowell's Discovery Channel Telescope (DCT). At Las Campanas Observatory (Chile), the 6.5 m Magellan-Baade telescope is equipped with IMACS (Inamori-Magellan Areal Camera & Spectrograph). This instrument is a wide-field imager with a 27.4' diameter field (8 CCDs) and a pixel scale of 0.20"/pixel. The short camera mode was used for all our runs. The Lowell's DCT (Happy Jack, Arizona) is equipped with the Large Monolithic Imager (LMI), a 6144x6160 pixels CCD (Levine et al. 2012SPIE.8444E..19L). The field of view is 12.5'x12.5', and 0.12"/pixel is the pixel scale. We use a range of exposure times between 250 and 900 s, depending on the telescope, the weather conditions, and the filter. Generally, broadband filters are selected to maximize the signal-to-noise ratio of the TNO (VR filter at DCT and WB4800-7800 filter at Magellan). Both filters cover a similar range, near 500-800 nm.
