report on behalf of the iPTF and GROWTH collaborations

We spatially cross-matched the LIGO/Virgo G299232 trigger (90% containment
volume using bayestar-HLV.fits; LVC GCN 21693Loading...
 
 ) with our Census of the Local
Universe (CLU; Cook et al. in prep) galaxy catalog and found 17,593
galaxies. This catalog is a compilation of galaxies with existing redshifts
from many sources (e.g., NED, SDSS, etc) and new galaxies from a 3PI
four-filter narrow-band survey to look for redshifted Halpha emission out
to 200 Mpc with the Palomar Oschin 48-inch telescope. Currently, the
narrow-band survey is only calibrated inside the footprint of SDSS. Of the
17,593 galaxies in the error volume, 17,120 come from a compilation of
known galaxies and 473 are new, emission-line CLU galaxy candidates derived
from our Halpha survey.

We list here the top 20 galaxies sorted by stellar mass (Mstar) for
galaxies whose location on the sky and distance falls in the 90% volume
reported by the BAYESTAR probability sky map (Singer et al. 2016). We also
list the dust-corrected star formation rates (SFRs) for galaxies with GALEX
FUV detections and a 'nan' for those with no detection.

The SFRs are derived from GALEX all sky kron FUV magnitudes via the
prescription of Murphy et al. (2011) and have been corrected for internal
dust extinction using a combination of GALEX FUV and 22um ALLWISE fluxes
(Hao et al. 2011). The quoted stellar masses are derived from 3.4um ALLWISE
fluxes and a mass-to-light ratio of 0.5 (McGaugh & Schombert et al. 2015).
