  Blazar flares seen by the Fermi Gamma-Ray Space Telescope Large Area
Telescope (Fermi LAT) are often followed up by Target of Opportunity (ToO)
requests to the Neil Gehrels Swift Observatory (Swift). Using flares identified
in the daily light curves of Fermi LAT Monitored Sources, we investigated which
follow-up Swift ToO requests resulted in refereed publications. The goal was to
create criteria of what Swift should look for in following up a Fermi-LAT
gamma-ray flare. Parameters tested were peak gamma-ray flux, flare duration
(based on a Bayesian Block analysis), type of AGN (BL Lac or FSRQ), and pattern
of activity (single flare or extensive activity). We found that historically
active sources and high-photon-flux sources result in more publications,
deeming these successful Swift ToOs, while flare duration and type of AGN had
little or no impact on whether or not a ToO led to a publication.
