/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 54562.084539 0.000370 0.23863 0.03771 0.96094 0 4.03682 0.27749 3.38595 0.23274 0.96330 0.13706 0.81013 0.11525 54562.085289 0.000379 0.22374 0.03541 0.97710 0 4.12499 0.27875 3.46126 0.23388 0.92292 0.13207 0.77441 0.11082 54562.086055 0.000388 0.23771 0.03828 0.98507 0 3.82316 0.26775 3.15303 0.22080 0.90879 0.13180 0.75034 0.10881 54562.086793 0.000350 0.22859 0.03607 0.98347 0 4.41127 0.30102 3.66425 0.25004 1.00837 0.14345 0.83736 0.11912 54562.087881 0.000738 0.30838 0.03202 0.97647 0 3.86090 0.19391 3.19834 0.16062 1.19064 0.10820 0.98718 0.08971 54562.089458 0.000839 0.32287 0.03076 0.96415 0 3.91754 0.18337 3.24344 0.15179 1.26484 0.10496 1.04765 0.08693 54562.151162 0.000324 0.29112 0.04670 0.97321 0 3.87280 0.29725 3.20378 0.24588 1.12746 0.15880 0.93250 0.13134 54562.151810 0.000324 0.27793 0.04551 0.99107 0 3.76450 0.28735 3.17863 0.24263 1.04627 0.15157 0.88340 0.12797 54562.152475 0.000341 0.25079 0.03962 0.95763 0 4.19237 0.29521 3.53400 0.24885 1.05142 0.14869 0.88643 0.12536 54562.153196 0.000379 0.26470 0.04221 0.93893 0 3.64136 0.26222 3.05442 0.21994 0.96386 0.13715 0.81008 0.11525 54562.153879 0.000304 0.33558 0.05498 0.98095 0 3.46867 0.28548 2.92540 0.24077 1.16401 0.16492 0.98170 0.13909 54562.154486 0.000304 0.34464 0.05644 0.96190 0 3.41179 0.28175 2.87755 0.23764 1.17585 0.16629 0.99175 0.14025 54562.155149 0.000359 0.27083 0.04362 0.95968 0 3.64633 0.26938 3.07529 0.22720 0.98753 0.14134 0.83288 0.11920 54562.156208 0.000694 0.23611 0.02752 0.97917 0 3.94984 0.20318 3.31177 0.17035 0.93261 0.09755 0.78204 0.08180
