Gaia DR3 catalogue within 3° of the centre of the Sextans dSph (grey dots), consisting of 94 770 objects that have photometry, proper motions, and parallax measurements. The horizontal and vertical axes are the local tangent plane co-ordinates corresponding to the right ascension and declination, respectively. The positions of the 41 VLT/FLAMES LR8 pointings(∼25′ diameter) are shown with dotted blue and full red circles. In blue are the 16 previously analysed fields, and in red are the 25 new fields presented here for the first time (with field IDs, as listed in Table A.1). The nominal tidal radius of Sextans from Irwin & Hatzidimitriou (1995) is shown as an orange ellipse.
