[Halld-offline] [EXTERNAL] Re: Building versions for Nacer, notes on analysis launch 1 (of 4).

[Sean Dobbs]

Mark,

If I remember correctly, 2016-02ver06 was reconstructed with the same
software as 2017-01ver03 at roughly the same time.  If we check the
website:
https://halldweb.jlab.org/cgi-bin/data_monitoring/monitoring/dataVersions.py
recon2016-02ver06 was reconstructed with the version set
version_recon_2016_02_ver06.xml  (I think there was a typo on the
page).  The link is broken, but if we can track the file down, that
would answer the question.

Data for analysis launches should be stored in here as well. but
perhaps that's a problem for version 2 of this database.
