/* ** ** 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 59777.917190 0.000602 0.26347 0.02105 0.99519 0 8.14932 0.29958 7.32985 0.26945 2.14710 0.15233 1.93048 0.13696 59777.918391 0.000599 0.27714 0.02270 0.97101 0 7.97316 0.30164 7.03964 0.26631 2.20971 0.16052 1.95124 0.14174 59777.919641 0.000651 0.24949 0.02002 0.99111 0 8.00373 0.28818 7.13721 0.25696 1.99685 0.14322 1.78196 0.12781 59777.920934 0.000642 0.26847 0.02148 0.97748 0 7.79387 0.28815 6.93425 0.25638 2.09240 0.14843 1.86381 0.13222 59777.922335 0.000758 0.21467 0.01691 0.96947 0 8.21788 0.27185 7.30478 0.24163 1.76410 0.12610 1.56865 0.11213 59777.923712 0.000619 0.27216 0.02192 0.98131 0 7.85111 0.29240 6.96739 0.25945 2.13672 0.15262 1.89282 0.13519 59777.924979 0.000648 0.26077 0.02087 0.99107 0 7.82598 0.28899 6.91580 0.25537 2.04075 0.14491 1.80429 0.12812 59777.926345 0.000718 0.24141 0.01884 0.99597 0 7.89723 0.27684 6.93668 0.24317 1.90646 0.13294 1.67462 0.11677
