/* ** ** Swift/XRT hardness ratio for Mrk 421. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56779.448593 0.000451 0.15169 0.01184 0.98077 0 22.04443 0.61541 17.00124 0.47400 3.34394 0.24378 2.57199 0.18755 56779.449461 0.000417 0.17682 0.01392 0.99306 0 19.71940 0.59834 15.55319 0.47191 3.48680 0.25333 2.75064 0.19977 56779.450285 0.000408 0.16899 0.01303 0.99291 0 21.52066 0.63609 16.82151 0.49715 3.63679 0.25892 2.84882 0.20279 56779.451127 0.000434 0.16136 0.01248 0.99333 0 21.03108 0.61009 16.49693 0.47862 3.39349 0.24324 2.66446 0.19094 56779.452036 0.000475 0.14580 0.01161 1.00000 0 20.67131 0.57661 16.15523 0.45061 3.01380 0.22484 2.35376 0.17562 56779.452970 0.000460 0.14644 0.01117 0.99371 0 22.09948 0.60353 17.24318 0.47088 3.23630 0.23038 2.52427 0.17969 56779.453865 0.000434 0.15113 0.01174 1.00000 0 22.25680 0.62545 17.41771 0.48945 3.36374 0.24369 2.63563 0.19092 56779.454921 0.000622 0.17449 0.01101 0.99450 0 20.64513 0.50238 16.30162 0.39667 3.60239 0.20978 2.84295 0.16554
