The final COS-B database - In-flight calibration of sensitivity and instrumental background behaviour

Strong, A. W.; Hermsen, W.; Lebrun, F. +3 more

This is one in a series of papers prepared in association with the release of the final COS-B database. Various aspects of the performance of the COS-B gamma-ray telescope are studied using in-flight data. First, the time-variation of the sensitivity and background over the 6.7 years of the mission is investigated. COS-B observed many regions of t…

COS-B upper limit to the greater than 70 MeV gamma-ray flux from a gamma-ray burst event of 1979 November 9

Clements, D. L.; Williams, O. R.; Sumner, T. J. +1 more

Using the COS-B data base an upper limit of 2×10^-7cm^-2s^-1keV^-1 has been set to the high energy (70 - 1000 MeV) gamma-ray burst flux from a gamma-ray burst event of 1979 November 9. This limit is consistent with a power law extension from the lower energy data with a differential index of ≤-1.39. An upper…
