/* ** ** 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 59679.159891 0.000544 0.27693 0.02278 0.98404 0 8.92381 0.34135 7.63320 0.29198 2.47124 0.17999 2.11528 0.15406 59679.160993 0.000558 0.26762 0.02186 0.98446 0 9.03879 0.33776 7.73534 0.28906 2.41898 0.17574 2.07016 0.15038 59679.162096 0.000544 0.26303 0.02128 0.96809 0 9.59774 0.35179 8.23967 0.30201 2.52447 0.18205 2.16726 0.15629 59679.163178 0.000538 0.28026 0.02302 0.98925 0 8.86224 0.34087 7.60884 0.29266 2.48373 0.18030 2.13242 0.15480 59679.164266 0.000550 0.29261 0.02385 0.98421 0 8.44076 0.32832 7.24663 0.28187 2.46981 0.17694 2.12041 0.15191 59679.165316 0.000501 0.31360 0.02595 0.97688 0 8.69003 0.35213 7.46077 0.30232 2.72517 0.19666 2.33968 0.16884 59679.166335 0.000518 0.29694 0.02454 0.98324 0 8.76634 0.34573 7.52640 0.29683 2.60304 0.18909 2.23483 0.16234 59679.167391 0.000538 0.27934 0.02276 0.97312 0 9.08645 0.34439 7.80135 0.29569 2.53822 0.18304 2.17923 0.15716 59679.169014 0.001085 0.27618 0.01594 0.98400 0 8.93417 0.23925 7.65021 0.20487 2.46742 0.12619 2.11375 0.10809
