Where to find galaxy mass function observational data?

In summary, galaxy mass function observational data is the measurement and observation of the distribution of galaxy masses in the universe. It can be found in databases and archives such as NED and SDSS, as well as in research papers. There are different types of data available, including photometric, spectroscopic, and imaging data. This data is used by scientists to study galaxies and test cosmological models. It is publicly available for research use, but proper citation and following usage guidelines is important.

Dear all,

I am looking for observational data for the number count of galaxy mass function:
\begin{equation} dn/dM\end{equation} in terms of redshift and also mass, to compare with theories.
I know that I can use HIPASS data (most probably), but as I am new to the field, I have to idea:
1- where to find the data
2- How to convert the observational data to dn/dM ?
