The KFRD detectors are similar to the HEPC detectors and hence have comparable scientific objectives and sensitivity. While the KFRD system has a somewhat better instrumental point response than HEPC, the SODART telescope system dominates the overall PSF determination. Therefore, for the purposes of this NRA, the KFRD detectors should be treated identically to HEPC. For detailed sensitivity calculations, see the sections on HEPC in this document. Count rate estimates may be made using the HEPC area and response in PIMMS and XSPEC.
