/* ** ** 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 59425.002760 0.000436 0.29464 0.08462 0.99892 1 2.94835 0.41665 0.72230 0.10207 0.86869 0.21718 0.21354 0.05338 59425.004136 0.000420 0.27728 0.04473 0.95172 0 3.02010 0.22471 2.59058 0.19273 0.83742 0.11987 0.71818 0.10279 59425.004984 0.000428 0.25231 0.04060 0.99324 0 3.09216 0.22737 2.66898 0.19622 0.78019 0.11167 0.67421 0.09650 59425.005739 0.000327 0.13840 0.03197 0.98230 0 3.33456 0.27181 2.83219 0.23085 0.46151 0.09976 0.39229 0.08479 59425.006540 0.000475 0.22369 0.03573 0.99390 0 3.15289 0.21768 2.70433 0.18669 0.70528 0.10158 0.60479 0.08709 59425.007452 0.000437 0.23682 0.03759 0.97351 0 3.31867 0.23335 2.85399 0.20065 0.78594 0.11182 0.67781 0.09643 59425.008436 0.000547 0.18695 0.02905 0.97884 0 3.35138 0.20926 2.87626 0.17956 0.62653 0.08914 0.53858 0.07662 59425.009535 0.000553 0.12771 0.02268 0.97382 0 3.59722 0.21647 3.07819 0.18522 0.45939 0.07676 0.39283 0.06564 59425.010623 0.000535 0.18838 0.02945 0.97297 0 3.42276 0.21511 2.92310 0.18369 0.64477 0.09229 0.55061 0.07881 59425.011642 0.000483 0.20464 0.03201 0.98204 0 3.48271 0.22618 2.97479 0.19318 0.71270 0.10141 0.60755 0.08644 59425.012654 0.000530 0.19205 0.02967 0.97814 0 3.50617 0.22054 2.98219 0.18753 0.67335 0.09503 0.57311 0.08087
