(i.e. the Swift-BAT team):
We report further analysis of GRB 141205A (Cummings, GCN 17137). The best
BAT position is RA, Dec 92.859, +37.876, which is:
RA (J2000) 06 11 26.1s
Dec (J2000) +37d 52' 32.2"
with an estimated position uncertainty of 2 arcmin radius. The source was
41% coded in BAT.
The unweighted lightcurve shows multiple weak peaks. T90 was 1.1 +- 0.2
seconds.
The total spectrum in BAT is best fit by a simple power-law function with
a photon index of 0.985 +- 0.002. The fluence in 1.4 seconds was
(1.2 +- 0.3) x 10^-7 ergs/cm^2. Errors are 90% confidence.
Because this burst was found in ground analysis, the normal automated burst
analysis products are not available.
