/* ** ** Swift/XRT hardness ratio for M87. ** 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 55298.298896 0.000747 0.21587 0.03896 0.70930 0 4.60022 0.40279 2.30441 0.20177 0.99306 0.15671 0.49638 0.07834 55298.300082 0.000434 0.19461 0.05269 0.74667 0 3.50876 0.45721 1.74551 0.22735 0.68283 0.16204 0.33923 0.08053 55298.300892 0.000376 0.16423 0.04468 0.77692 0 4.49622 0.53361 2.23824 0.26554 0.73841 0.18078 0.36591 0.08959 55298.301957 0.000689 0.23690 0.04193 0.73950 0 4.46752 0.39023 2.23423 0.19513 1.05836 0.16292 0.52790 0.08124 55298.303386 0.000741 0.23470 0.04148 0.75391 0 4.08276 0.34718 2.03382 0.17292 0.95824 0.14844 0.47872 0.07413 55298.304845 0.000718 0.21982 0.03875 0.74194 0 4.59738 0.38646 2.28202 0.19181 1.01058 0.15657 0.50213 0.07776 55298.306344 0.000781 0.24189 0.04356 0.71111 0 3.95378 0.35006 1.96607 0.17406 0.95640 0.14998 0.47581 0.07461 55298.307796 0.000671 0.25525 0.04630 0.73707 0 4.24989 0.39374 2.10942 0.19538 1.08480 0.16918 0.53727 0.08372 55298.309116 0.000648 0.24437 0.04591 0.78571 0 4.11325 0.37666 2.04655 0.18733 1.00517 0.16487 0.49845 0.08177 55298.310151 0.000370 0.16983 0.04393 0.82812 0 4.48171 0.52291 2.22785 0.25985 0.76113 0.17573 0.37733 0.08716 55298.310985 0.000463 0.12972 0.03292 0.73125 0 5.10778 0.50385 2.53667 0.25025 0.66256 0.15493 0.32916 0.07696 55298.312226 0.000778 0.22143 0.04165 0.74721 0 3.95009 0.35655 1.95568 0.17654 0.87468 0.14436 0.43388 0.07165 55298.313407 0.000396 0.17196 0.04804 0.73723 0 4.15883 0.49488 2.06439 0.24563 0.71515 0.18074 0.35565 0.08988 55298.314538 0.000735 0.23881 0.04166 0.76772 0 4.07980 0.35575 2.03226 0.17723 0.97429 0.14721 0.48444 0.07318 55298.315745 0.000472 0.16509 0.04384 0.71166 0 4.31768 0.50582 2.14158 0.25097 0.71282 0.16988 0.35253 0.08402 55298.317145 0.000929 0.22569 0.03737 0.74977 0 4.10884 0.33803 2.05065 0.16868 0.92734 0.13325 0.46223 0.06642 55298.364710 0.000590 0.16351 0.03677 0.71569 0 2.65275 0.24916 2.23521 0.20993 0.43374 0.08864 0.36540 0.07468 55298.366298 0.000992 0.19254 0.02942 0.78134 0 2.81629 0.19649 2.36267 0.16483 0.54225 0.07371 0.45555 0.06191
