We observed 8 masks in seven different clusters during the two nights LDSS3 run in March30-31, 2017. The first night was good with average seeing ranging between 0.7-0.8", while the seeing was slightly poor (1.0-1.3") during the second night. We detected emission lines in 23 lensed galaxies in five different clusters. Redshift confirmation wasn't possible in two (RXCJ0911 & PSZ2 G209) out of seven observed clusters. Below are my estimation of redshifts along with the position (RA,DEC) of the emission line sources identified in the LDSS3 data:
