Most recent saved and unclassified sources from ZTF - CATS150


The sources listed below have been checked to be within the CATS150 volume (<150 Mpc). They also have peak apparent magnitude brighter than 20.0. Most have been assigned spectroscopic followup, some are yet be classified.
For these sources, please double-check the physical separation from the NED LVS galaxy (within 30 kpc for z>0.01 and/or perform a visual check), subtractions, and reference images prior to observing.
The peak absolute magnitude is provided to assist in identifaction of faint sources likely to be nearby nova and other non-SN phenomena that contaminate the CATS150 experiment completeness but may still be worth following up.
The zNED column may be inaccurate for very nearby sources such as M31 or M33 where automatic cross-matching found a background galaxy farther away. Such cases were identified as sources with no redshift entry and a cross-matched NED galaxy with a negative redshift. In these instances, the row is highlighted in light red to indicate the unreliable redshift and quantities calculated from that redshift. Additionally, the peak absolute magnitude for these nearby sources is now calculated assuming a distance of 1 Mpc, slightly farther away than the usual nearby galaxy culprits M31 (~0.7-0.8 Mpc) and M33 (~0.8-0.9 Mpc).
