Originally published in 2016ApJ...819...62CThe half-a-field shift tiling strategy was designed to uniformly cover the COSMOS Hubble area in depth and point-spread function (PSF) size by combining the old C-COSMOS (Elvis+, 2009, J/ApJS/184/158) observations with the new Chandra ones (see Figure 1). We summarize the main properties of the new ACIS-I Chandra COSMOS-Legacy observations in Table 1. The observations took place in four blocks 2012 November to 2013 January; 2013 March to July; 2013 October to 2014 January; and 2014 March. The mean net effective exposure time per field was 48.8ks after all the cleaning and reduction operations.
