/* ** ** 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 54586.094800 0.000425 0.32086 0.05232 0.97959 0 6.57346 0.53676 2.19040 0.17844 2.10917 0.29771 0.70593 0.09942 54586.095596 0.000370 0.28900 0.04660 0.95312 0 8.06447 0.61116 2.83096 0.21445 2.33061 0.33169 0.81681 0.11619 54586.096397 0.000431 0.28415 0.04626 0.98658 0 6.91288 0.53611 2.36672 0.18348 1.96427 0.28119 0.67438 0.09649 54586.097384 0.000556 0.19530 0.03025 0.97396 0 7.95686 0.50187 2.73823 0.17270 1.55399 0.21981 0.53565 0.07575 54586.098475 0.000535 0.22261 0.03515 0.96216 0 7.33095 0.48929 2.50643 0.16727 1.63191 0.23351 0.55694 0.07969 54586.099540 0.000530 0.19650 0.03079 0.97268 0 8.43312 0.53838 2.82562 0.18034 1.65710 0.23711 0.55694 0.07969 54586.100567 0.000498 0.22654 0.03631 0.98256 0 7.64449 0.52251 2.58310 0.17654 1.73177 0.25104 0.58623 0.08498 54586.101655 0.000590 0.20231 0.03192 0.96569 0 7.19390 0.46482 2.47281 0.15973 1.45542 0.20949 0.50060 0.07205 54586.102743 0.000498 0.23709 0.03757 0.96512 0 7.42848 0.51448 2.55521 0.17695 1.76126 0.25099 0.60616 0.08635 54586.103776 0.000535 0.21550 0.03444 0.98378 0 7.23415 0.49011 2.50297 0.16954 1.55895 0.22568 0.53902 0.07804 54586.104728 0.000417 0.30308 0.04924 0.97222 0 6.83166 0.53552 2.34712 0.18386 2.07057 0.29463 0.71179 0.10125 54586.105555 0.000411 0.29134 0.04793 0.96479 0 7.15143 0.55814 2.44822 0.19103 2.08346 0.30170 0.71608 0.10367 54586.106785 0.000819 0.25507 0.03111 0.99293 0 7.00043 0.38618 2.41820 0.13339 1.78563 0.19424 0.61636 0.06703
