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 768Not found
 
 
) and GRB000730 (GCN
772Not found
 
 
) may be interpreted on the basis of above mentioned data.
       This message is quotable in publications.
