We are performing a flux limited transient survey based on the MSIP all sky survey. The standard in this field is set by ASAS-SN which is by our estimate complete to less than 17 mag. The experimental goal of the ZTF RCF project is to classify transients (which are mostly SNe) to a peak magnitude, m_p of about 18.5 mag. In practice, this means classifying transients which are a few tenths mag fainter (~18.75). Flux limited surveys serve many purposes, and are essential for e.g., computing rates. We have a specific novel goal: use SN of type Ia to evaluate the red-shift completeness factor (RCF) of catalog(s) of nearby (<200 Mpc).
