/* ** ** 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 59962.027068 0.000492 0.21336 0.00756 1.00000 0 60.08412 0.88941 54.65138 0.80893 12.81958 0.41243 11.65409 0.37492 59962.028055 0.000495 0.21400 0.00763 1.00000 0 59.03739 0.88259 53.91767 0.80598 12.63396 0.40877 11.53538 0.37322 59962.029053 0.000503 0.20559 0.00733 0.99425 0 60.79321 0.88910 55.33219 0.80919 12.49854 0.40663 11.38557 0.37034 59962.029675 0.000119 0.17521 0.01359 1.00000 0 62.30253 1.89200 56.01437 1.70086 10.91602 0.77935 9.81095 0.70035 59962.030291 0.000498 0.20961 0.00735 1.00000 0 61.20570 0.89785 55.43858 0.81320 12.82933 0.40865 11.61788 0.36999 59962.031266 0.000477 0.21760 0.00767 1.00000 0 60.84257 0.90972 55.53921 0.83039 13.23962 0.42261 12.08519 0.38573 59962.032244 0.000501 0.20568 0.00726 1.00000 0 61.12541 0.89203 55.73112 0.81328 12.57243 0.40429 11.46357 0.36860 59962.033251 0.000506 0.20352 0.00720 1.00000 0 61.09080 0.88748 55.58561 0.80747 12.43313 0.40073 11.30846 0.36443 59962.034591 0.000833 0.22371 0.00593 0.99879 0 60.77050 0.69255 55.14153 0.62834 13.59482 0.32526 12.32670 0.29492
