Notes:
The host galaxy of CSS101113:030504-194039 is not seen in DSS or Palomar Quest
coadd images reaching V ~ 22, but is clearly seen in deep archival CFHT megaprime
images. Based on the SNID fit redshift, the host galaxy has Mi~-12.7 and Mg~-13.0.
The host galaxy is therefore an intrinsically faint galaxy consistent with many
similar SN hosts observed by CRTS (e.g. ATel#2447, ATel#1950, ATel#1860, ATel#1856).
CSS110114:091354-170039 and CSS101213:015021-214432 are relatively luminous SNe
having Mv < -19.7.
