/* ** ** 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 57871.098455 0.000576 0.29093 0.04726 0.98492 0 3.38642 0.26416 1.77579 0.13820 0.98521 0.14039 0.50841 0.07232 57871.099674 0.000642 0.20890 0.03316 0.95045 0 4.21439 0.28219 2.23863 0.14990 0.88040 0.12670 0.46735 0.06727 57871.100877 0.000561 0.26546 0.04286 0.97423 0 3.74647 0.28016 1.97504 0.14766 0.99456 0.14231 0.52449 0.07505 57871.101994 0.000556 0.23490 0.03763 0.97396 0 4.21709 0.29646 2.24338 0.15771 0.99058 0.14259 0.52733 0.07590 57871.102868 0.000318 0.20112 0.05007 0.94545 0 3.55392 0.36387 1.88636 0.19314 0.71475 0.16218 0.38027 0.08629 57871.103623 0.000437 0.34281 0.05641 0.96026 0 3.75083 0.31543 2.02106 0.16993 1.28581 0.18185 0.69081 0.09769 57871.104642 0.000582 0.24984 0.04028 0.98507 0 3.75608 0.27256 1.99690 0.14490 0.93841 0.13510 0.49803 0.07169 57871.105738 0.000515 0.26979 0.04307 0.96067 0 4.09422 0.30333 2.17215 0.16092 1.10458 0.15622 0.58577 0.08284 57871.106893 0.000639 0.24645 0.03907 0.98190 0 3.53531 0.25325 1.87517 0.13432 0.87127 0.12322 0.46160 0.06528 57871.108259 0.000726 0.20498 0.03269 0.97211 0 3.82287 0.24755 2.05668 0.13315 0.78362 0.11421 0.42179 0.06141
