TITLE: GCN GRB OBSERVATION REPORT NUMBER: 773 SUBJECT: GRB000801 & GRB000730, Gamma Ray Observations DATE: 00/08/17 15:10:08 GMT FROM: Srikanta Sinha at ISRO/ISAC S.Sinha, P.Sreekumar, K.Kasturirangan, on behalf of SROSS C-2 (INDIAN GRB EXPERIMENT) team report: The hardness ratios (during the peak of the bursts) for GRB000801 and GRB000730 were reported by us to be 0.27+-0.08 and 0.47 +-0.082 respectively. Our hardness ratio is defined as [counts(100-1024 keV)/counts(20-100 keV)]. For twenty-one SROSS C-2 GRBs that are common with BATSE, we find the mean hardness ratio to be 0.97 +- 0.079 and the standard deviation of this distribution is 0.37. The hardness ratios for the GRB000801 (GCN 768) and GRB000730 (GCN 772) may be interpreted on the basis of above mentioned data. This message is quotable in publications. -Srikanta Sinha, on behalf of the SROSS C-2 (INDIAN GRB EXPT. TEAM) at the Technical Physics Division, ISRO Satellite Center, Bangalore-560 017,INDIA.
