/* ** ** 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 54923.063484 0.000324 0.26597 0.04267 0.95536 0 4.14608 0.30030 3.49423 0.25308 1.10272 0.15787 0.92618 0.13258 54923.064143 0.000336 0.27391 0.04429 1.00000 0 3.69591 0.27795 3.12065 0.23469 1.01236 0.14492 0.85432 0.12229 54923.064910 0.000431 0.18021 0.02782 0.96644 0 4.52798 0.27127 3.83778 0.22992 0.81597 0.11610 0.69190 0.09844 54923.065657 0.000315 0.28123 0.04525 0.97248 0 3.93411 0.29554 3.33644 0.25064 1.10641 0.15742 0.93994 0.13373 54923.066389 0.000417 0.20458 0.03209 0.95139 0 4.14372 0.26559 3.53553 0.22660 0.84773 0.12135 0.72337 0.10355 54923.067193 0.000388 0.24334 0.03790 0.94030 0 3.89883 0.26574 3.33197 0.22710 0.94876 0.13285 0.81087 0.11354 54923.067893 0.000312 0.30360 0.04975 0.98148 0 3.60052 0.28715 3.07961 0.24560 1.09310 0.15647 0.93492 0.13383 54923.068834 0.000628 0.20749 0.02520 0.97924 0 4.35769 0.22047 3.72477 0.18845 0.90420 0.09985 0.77307 0.08537 54923.128496 0.000318 0.24386 0.03918 0.98182 0 4.37572 0.31000 3.78030 0.26777 1.06707 0.15386 0.92178 0.13291 54923.129246 0.000431 0.19758 0.03078 0.92617 0 4.19488 0.25804 3.63747 0.22374 0.82881 0.11861 0.71826 0.10279 54923.130007 0.000330 0.25275 0.03997 0.98246 0 4.13876 0.29756 3.59188 0.25823 1.04608 0.14733 0.90756 0.12782 54923.130698 0.000362 0.25675 0.04144 0.95200 0 3.73024 0.27214 3.22860 0.23554 0.95774 0.13790 0.82854 0.11928 54923.131404 0.000344 0.25666 0.04139 0.96639 0 3.89148 0.28064 3.36611 0.24273 0.99880 0.14405 0.86567 0.12482 54923.132113 0.000365 0.25253 0.03997 0.96032 0 3.80392 0.26838 3.30909 0.23347 0.96059 0.13609 0.83573 0.11840 54923.132793 0.000315 0.26313 0.04165 0.97248 0 4.19231 0.30277 3.64434 0.26320 1.10312 0.15537 0.95893 0.13506 54923.133867 0.000758 0.27702 0.02823 0.95038 0 4.11334 0.19315 3.57952 0.16808 1.13947 0.10306 0.99134 0.08967 54923.134992 0.000367 0.27030 0.03881 0.98425 0 4.22425 0.28305 3.67519 0.24626 1.14182 0.14501 0.99365 0.12619 54923.135727 0.000367 0.24488 0.03702 0.95276 0 4.29263 0.28539 3.73331 0.24820 1.05120 0.14273 0.91418 0.12412
