/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** 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 55153.777450 0.000712 0.69056 0.20076 0.95918 1 0.31711 0.05890 0.24681 0.04583 0.21898 0.04898 0.17021 0.03806 55153.778569 0.000407 1.17602 0.38795 0.96429 1 0.32260 0.07824 0.25185 0.06108 0.37939 0.08483 0.29630 0.06625 55153.779716 0.000741 0.53651 0.14822 0.96078 1 0.39054 0.06336 0.30400 0.04932 0.20953 0.04685 0.16327 0.03651 55153.781212 0.000755 1.05959 0.34132 0.94231 1 0.19850 0.04580 0.15429 0.03559 0.21033 0.04728 0.16245 0.03652 55153.782694 0.000726 0.61575 0.17575 0.98000 1 0.34141 0.06055 0.26584 0.04715 0.21022 0.04701 0.16327 0.03651 55153.784277 0.000857 0.62946 0.18173 0.98305 1 0.27882 0.05008 0.21755 0.03907 0.17550 0.03967 0.13656 0.03086 55153.786311 0.001177 0.72444 0.16637 0.98274 1 0.29427 0.04408 0.22799 0.03415 0.21318 0.03711 0.16583 0.02887 55153.844135 0.000755 0.62789 0.17573 1.00000 1 0.31415 0.05504 0.25726 0.04507 0.19725 0.04305 0.16154 0.03525 55153.845573 0.000683 0.56380 0.15839 0.97872 1 0.37827 0.06433 0.30933 0.05260 0.21326 0.04769 0.17391 0.03889 55153.847070 0.000813 0.76071 0.22855 0.98214 1 0.23149 0.04615 0.18963 0.03780 0.17610 0.03959 0.14473 0.03253 55153.848566 0.000683 0.64205 0.18498 0.97872 1 0.32692 0.05892 0.26870 0.04842 0.20990 0.04718 0.17304 0.03890 55153.849946 0.000697 0.70418 0.20681 0.97917 1 0.29293 0.05578 0.24174 0.04603 0.20628 0.04612 0.17021 0.03806 55153.851137 0.000494 0.83617 0.25767 1.00000 1 0.33848 0.07090 0.27758 0.05814 0.28303 0.06397 0.23294 0.05264 55153.852023 0.000392 1.13290 0.37372 1.00000 1 0.31693 0.07687 0.26154 0.06343 0.35905 0.08029 0.29630 0.06625 55153.853621 0.001206 0.55564 0.13592 0.96165 1 0.28411 0.04153 0.23450 0.03428 0.15786 0.03096 0.13030 0.02555
