Notes. a For sources in which radio continuum emission is not detected, we report the 3 σ upper limit to the intensity (in mJy beam−1). b For sources in which maser emission is not detected, we also report the 3 σ upper limit, using the noise level (in mJy beam−1), measured at the position and channel map with the VLSR of the reported OH maser from single-dish observations. c UC: undetected continuum emission. UM: undetected maser emission. d This object is a new OHPN candidate, but we have included it in this table because we did not detect any H2O maser nor radio continuum emission in our VLA observations (see Appendix C.3.6).
