/* ** ** 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 56633.530271 0.000373 0.16407 0.01288 0.97674 0 20.77943 0.60429 19.01310 0.55291 3.40918 0.24853 3.12363 0.22771 56633.531024 0.000379 0.15564 0.01223 1.00000 0 20.98213 0.60393 19.21986 0.55322 3.26564 0.23869 2.98911 0.21849 56633.531773 0.000370 0.16497 0.01267 0.99219 0 21.21126 0.61496 19.22201 0.55726 3.49912 0.24888 3.17354 0.22566 56633.532508 0.000365 0.16294 0.01271 0.98413 0 21.73693 0.62901 19.57617 0.56644 3.54184 0.25654 3.18867 0.23092 56633.533243 0.000370 0.16585 0.01304 1.00000 0 20.42782 0.60308 18.57672 0.54844 3.38786 0.24697 3.07482 0.22415 56633.533972 0.000359 0.16359 0.01260 1.00000 0 21.65681 0.62708 19.89598 0.57607 3.54282 0.25290 3.25181 0.23215 56633.534861 0.000530 0.15049 0.01036 0.97662 0 21.21278 0.51470 19.40189 0.47067 3.19230 0.20568 2.91561 0.18786
