TITLE: GCN CIRCULAR NUMBER: 36605 SUBJECT: Swift Trigger 1232465: consistent with noise DATE: 24/06/03 07:33:30 GMT FROM: K.L. Page at U Leicester klp5@leicester.ac.uk
A. Y. Lien (U. Tampa) and K. L. Page (U. Leicester) report on behalf of the Swift team:
Using the full data set from recent downlinks, we report further ground data analysis for Swift trigger 1232465 (Gropp et al. GCN Circ. 36593).
The BAT analysis uses data from T-61 to T+302 sec. The BAT image significance has now decreased to 5.3 sigma (15-350 keV). Also, the mask-weighted light curve does not show anything significantly above the noise fluctuation.
Analysing the 1.2 ks of XRT data collected between 107 s and 6 ks after the trigger, no source is detected to a 3-sigma upper limit range of 0.007 - 0.011 count s^-1 (0.3-10 keV) within the BAT error circle.
We thus conclude that this trigger was consistent with noise fluctuations.
