Notes. Column 1: source name. Column 2: optical redshift. Column 3: observational epoch. Column 4: central frequency of the OH 1667 MHz line. Columns 5 and 6: scan length for each target-ON observation and number of cycles for on/off observations. Columns 7 and 8: spectral resolution in km s−1 and the 1σ noise level around the OH 1667 MHz line. Columns 9 and 10: σ noise near the binned OH 1612 and 1720 MHz lines with a velocity resolution about 10 km s−1. Columns 11 and 12: upper limit of integrated 1612 and 1720 MHz lines estimated with Eq. (1) in McBride et al. (2013).
