ABOUT
Here we describe the release of the measurements of the Galaxy Stellar Mass Function 
and quiescent mass fractions based on the DAWN PL Catalogues of EDFN and EDFF and LePhare estimates of
redshifts, masses, and rest-frame colours as described in Zalesky et al. 2025 (arXiv:2504.17867).

When using these data products please cite both this SMF paper
and the Catalogue paper. Links to ADS export citations:

SAMPLE SELECTION
These results were measured from a selection of reliable objects in the DAWN PL Catalogue. 
A FITS table with three boolean columns are included, indicating the selection ('True') of
objects within each category of 'tot', 'sf', and 'q' (total, star-forming, and quiescent, respetively).
See Section 3.1 of the SMF paper. Note that objects below the mass completeness limits are included
by this boolean selection.

   ./SMF_sample_selections.fits

	Further, note that to use the selections, one must combine the two separate catalogues as follows
   	(in python), creating one master catalogue, referred to below as 'cat':

	> edfn = Table.read('/path/to/DAWN_EDFN_DR1_{version}.fits') # read the EDFN table
	> edff = Table.read('/path/to/DAWN_EDFF_DR1_{version}.fits') # read the EDFF table
	> edff['ID'] = edff['ID'] + np.max(edfn['ID'])               # adjust the IDs so they remain unique
	> cat = astropy.table.vstack([edfn,edff])                    # vertically stack the tables


OBSERVED MASS FUNCTIONS
The observed mass functions for the total, star-forming, and quiescent samples are
provided as FITS tables, one per redshift bin, showing only mass complete measurements.
Below, the term 'samp' refers to either the total SMF ('tot'), star-forming SMF ('sf'), or the
quiescent SMF ('q'). The term 'zbin' refers to the redshift bin (see SMF paper for details).
