/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 55604.379932 0.000735 0.09880 0.02318 0.97638 0 1.97766 0.14042 1.63639 0.11618 0.19540 0.04370 0.16156 0.03613 55604.381430 0.000764 0.09610 0.02282 0.96970 0 1.93521 0.13532 1.60771 0.11242 0.18597 0.04219 0.15450 0.03505 55604.383233 0.001039 0.06407 0.01543 0.95543 0 2.11429 0.12137 1.75095 0.10051 0.13546 0.03168 0.11230 0.02625 55604.385157 0.000885 0.08904 0.02057 0.97386 0 1.89096 0.12537 1.56257 0.10359 0.16837 0.03726 0.13944 0.03086 55604.386792 0.000749 0.10418 0.02453 0.98070 0 1.82421 0.13455 1.51413 0.11168 0.19004 0.04249 0.15774 0.03527 55604.388262 0.000720 0.11660 0.02754 0.95984 0 1.74434 0.13243 1.44090 0.10938 0.20339 0.04548 0.16764 0.03749 55604.389547 0.000564 0.13961 0.03382 0.95897 0 1.82522 0.15498 1.51496 0.12864 0.25481 0.05782 0.21150 0.04799 55604.390805 0.000694 0.11211 0.02646 0.97917 0 1.84991 0.13957 1.52160 0.11480 0.20740 0.04638 0.17050 0.03812 55604.392605 0.001105 0.09062 0.01759 0.96597 0 2.13051 0.12047 1.73522 0.09811 0.19306 0.03585 0.15744 0.02924
