/* ** ** 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 55980.337462 0.000318 0.10510 0.01545 0.98182 0 10.58932 0.47498 9.10495 0.40839 1.11294 0.15583 0.95692 0.13398 55980.338839 0.001059 0.12315 0.00934 0.99180 0 10.35048 0.25857 8.89594 0.22223 1.27465 0.09126 1.09563 0.07844 55980.341012 0.001114 0.11803 0.00893 0.99481 0 10.20540 0.25038 8.77585 0.21530 1.20455 0.08624 1.03535 0.07413 55980.343217 0.001091 0.12176 0.00925 0.98143 0 10.25251 0.25408 8.78674 0.21774 1.24834 0.08960 1.06949 0.07677 55980.344603 0.000295 0.11557 0.01745 1.00000 0 9.78499 0.47795 8.42744 0.41164 1.13084 0.16153 0.97393 0.13912 55980.345234 0.000336 0.09054 0.01363 0.99138 0 10.98466 0.47311 9.46121 0.40750 0.99459 0.14350 0.85665 0.12360 55980.347083 0.001513 0.13358 0.00829 0.97323 0 10.25369 0.21551 8.80901 0.18515 1.36967 0.07999 1.17633 0.06870
