Hi,
Do we need to perform level 3 binning for every file? I am just doing like level 2 binning and bl3 map to make mapped version of that file. And I am using default flags. I processed almost 3 years data. Is it necessary to perform the level 3 binning?

l2bin takes L2 files and creates a L3 file
l3bin takes L3 files and creates another L3 file.

Generally, one would bin the L2 files for a given day using l2bin,
then create longer time period bins (8-day, monthly, seasonal, etc.)
from the daily L3 files.  However, if given all the L2 files for the
time period of interest, l2bin will create an identical file to l3bin
following the above convention.

Sean
