Derived mean count rate
WebDerived rates calculate their prices by adding or subtracting amounts (Derived Amount rate) or percentage (Derived Percent Rate) to/from an existing standard rate. When the prices in a standard rate change, the prices in the rates derived from it change automatically as well. WebHowever, users should note that this method for calculating the MOE and SE for aggregated count data is an approximation, and caution is warranted because this method does not consider the correlation or covariance between the component estimates. This method may result in an overestimate or underestimate of the derived

WebNov 23, 2024 · This hardness ratio is calculated from the source counts in the PSPC and defined as HR 1 = (B-A)/ (B+A), where A is the PSPC channel range 11-41 and B is the PSPC channel range 52-201. Each channel can be approximately converted to energy by multiplying the channel number by 10 eV.
