  We present and validate the catalog of Lyman-$\alpha$ forest fluctuations for
3D analyses using the Early Data Release (EDR) from the Dark Energy
Spectroscopic Instrument (DESI) survey. We used 88,511 quasars collected from
DESI Survey Validation (SV) data and the first two months of the main survey
(M2). We present several improvements to the method used to extract the
Lyman-$\alpha$ absorption fluctuations performed in previous analyses from the
Sloan Digital Sky Survey (SDSS). In particular, we modify the weighting scheme
and show that it can improve the precision of the correlation function
measurement by more than 20%. This catalog can be downloaded from
https://data.desi.lbl.gov/public/edr/vac/edr/lya/fuji/v0.3 and it will be used
in the near future for the first DESI measurements of the 3D correlations in
the Lyman-$\alpha$ forest.
