UVIT F169M filter image of E3. The half-light and tidal radius of E3 (Rh = 2.1′ and Rt = 8.49′, Harris 1996, 2010) are well within the field of view of UVIT. The red arrow indicates the probable post-AGB star. In the inset (upper right corner) the optical V-band image (Stetson et al. 2019) of the cluster (up to half-light radius) is shown. The PAGB star is easily distinguishable as one of the cluster’s brightest stars in both images.
