Notes. We only list candidates that were first reported to the TNS after 7 Aug (one week prior to the GW event), and that were discovered up to two weeks after the GW event. The “Comments” column lists the reason why candidates were discounted: Non.Det. = no subsequent detection after first report; Ast = asteroid, moving object; Spec.Host-z = spectroscopic redshift of host is inconsistent with GW; Phot.Host-z = photometric redshift of host is inconsistent with GW (we note that photometric redshifts are reported to one decimal place in the redshift column); SN = spectroscopically classified as a supernova; SN? = probable supernova; Pre.Det. = historical detection in survey data prior to S190814bv; HPM = high proper motion star; AGN/AGN? = active galactic nucleus flare or other nuclear transient (or probable nuclear transient); Andreoni = candidates which are reported and ruled out in Andreoni et al. (2020). Candidates which we are unable to classify are indicated with “?”. Objects with an asterisk in the comment column are discussed in more detail in the text of Appendix C. (a)Not reported in GCN, candidate announced on TNS and in Andreoni et al. (2020). (b)References for GCNs listed in the table: Soares-Santos et al. (2019a), De et al. (2019b), Goldstein et al.
