/* ** ** 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 55669.897270 0.000333 0.28030 0.04530 0.94783 0 3.81620 0.28612 3.24267 0.24311 1.06968 0.15316 0.90899 0.13015 55669.897942 0.000339 0.24673 0.03966 0.97436 0 4.22137 0.29797 3.53808 0.24973 1.04155 0.15040 0.87239 0.12595 55669.898599 0.000318 0.29091 0.04700 0.98182 0 3.76618 0.29417 3.19174 0.24930 1.09562 0.15495 0.92747 0.13116 55669.899273 0.000356 0.31593 0.04787 0.95121 0 3.70062 0.27514 3.12875 0.23262 1.16914 0.15434 0.98847 0.13049 55669.900034 0.000405 0.22331 0.03535 0.96429 0 3.89580 0.26261 3.28237 0.22124 0.86999 0.12459 0.73392 0.10509 55669.900763 0.000324 0.23775 0.03767 1.00000 0 4.43811 0.31710 3.76641 0.26910 1.05516 0.14923 0.89435 0.12648 55669.901391 0.000304 0.30536 0.05001 0.98095 0 3.72540 0.29609 3.14980 0.25032 1.13760 0.16291 0.96194 0.13773 55669.902027 0.000327 0.26250 0.04141 1.00000 0 4.12162 0.29937 3.44564 0.25027 1.08192 0.15151 0.90416 0.12661 55669.902687 0.000333 0.26659 0.04330 0.99130 0 3.81521 0.28601 3.24222 0.24306 1.01712 0.14654 0.86435 0.12453 55669.903434 0.000414 0.19381 0.02994 0.97203 0 4.44245 0.27589 3.71359 0.23061 0.86101 0.12178 0.72062 0.10191 55669.904186 0.000339 0.24192 0.03844 0.98291 0 4.27504 0.30196 3.57716 0.25263 1.03421 0.14720 0.86629 0.12327 55669.904820 0.000295 0.28224 0.04568 0.99020 0 4.19481 0.32352 3.49419 0.26946 1.18396 0.16848 0.98637 0.14036 55669.905503 0.000388 0.23570 0.03724 0.97015 0 3.84407 0.26385 3.25378 0.22332 0.90606 0.12893 0.76633 0.10905 55669.906203 0.000312 0.31543 0.05008 0.99074 0 3.70642 0.28972 3.10987 0.24305 1.16912 0.16154 0.98723 0.13640 55669.906917 0.000402 0.24535 0.03874 0.96403 0 3.62787 0.25208 3.06832 0.21321 0.89010 0.12619 0.75435 0.10692 55669.907823 0.000503 0.28685 0.03730 0.98851 0 3.70507 0.22870 3.11113 0.19203 1.06281 0.12162 0.89368 0.10225
