S. Campana, L. Foschini, G. Tagliaferri, G. Ghisellini,
S. Covino (INAF-OAB) report:
We retrieved Fermi LAT publicly available data in near-real time
from http://fermi.gsfc.nasa.gov/cgi-bin/ssc/LAT/LATDataQuery.cgi
to search for high energy emission from GRB 110328 /
Swift J164449.3+573451 within the time interval:
2011-03-27 00:00:00 UTC
2011-03-31 00:00:00 UTC
We used LAT Science Tools 9.18.6 and the corresponding calibration
files to perform the analysis. We analyzed data for each of the four
days and in none of the corresponding datasets we detect the
source.
Following Foschini et al. (2011, http://arxiv.org/abs/1101.1085),
we derived a 3 sigma upper limit of ~3x10^-7 ph/cm2/s in the
0.1-100 GeV energy band in each exposure (lasting 4-5 ks).
