/* ** ** 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 56509.615397 0.000365 0.24706 0.03969 0.97619 0 3.73930 0.26650 3.24383 0.23119 0.92385 0.13302 0.80155 0.11541 56509.616155 0.000394 0.24344 0.03871 0.99265 0 3.53849 0.25130 3.02611 0.21490 0.86142 0.12255 0.73808 0.10500 56509.616997 0.000448 0.21050 0.03315 0.97419 0 3.68749 0.24222 3.11475 0.20459 0.77621 0.11110 0.65640 0.09394 56509.617848 0.000402 0.24265 0.03783 0.98561 0 3.68171 0.25657 3.11410 0.21700 0.89336 0.12461 0.75655 0.10552 56509.618699 0.000448 0.20606 0.03181 0.95484 0 3.94001 0.24887 3.34292 0.21113 0.81189 0.11435 0.68679 0.09673 56509.619521 0.000373 0.24154 0.03814 0.96899 0 3.92268 0.27529 3.31568 0.23268 0.94750 0.13400 0.80133 0.11333 56509.620322 0.000428 0.20932 0.03296 0.97297 0 3.88736 0.25498 3.28415 0.21540 0.81371 0.11647 0.68830 0.09851 56509.621109 0.000359 0.29184 0.04729 0.98387 0 3.28806 0.25504 2.79153 0.21652 0.95959 0.13653 0.81673 0.11619 56509.621835 0.000367 0.27329 0.04405 0.97638 0 3.46011 0.25660 2.92811 0.21712 0.94563 0.13531 0.79932 0.11440 56509.622605 0.000402 0.23879 0.03794 0.95683 0 3.67280 0.25342 3.12018 0.21525 0.87704 0.12553 0.74523 0.10666 56509.623337 0.000330 0.27690 0.04455 0.99123 0 3.76855 0.28294 3.17918 0.23869 1.04353 0.14847 0.88178 0.12545 56509.624121 0.000454 0.20038 0.03089 0.97452 0 3.93268 0.24654 3.31424 0.20777 0.78803 0.11100 0.66434 0.09357 56509.624957 0.000382 0.24033 0.03823 1.00000 0 3.72895 0.26525 3.13831 0.22324 0.89618 0.12750 0.75486 0.10739 56509.625669 0.000330 0.25414 0.04103 0.99123 0 4.03010 0.29403 3.43209 0.25040 1.02422 0.14749 0.87248 0.12562 56509.626367 0.000367 0.29371 0.04296 0.96850 0 3.98769 0.27750 3.36743 0.23432 1.17121 0.15070 0.98925 0.12728 56509.627162 0.000428 0.23646 0.03756 0.98649 0 3.43006 0.24232 2.88635 0.20391 0.81107 0.11539 0.68247 0.09709 56509.628007 0.000417 0.24135 0.03877 0.95139 0 3.48967 0.24240 2.96129 0.20568 0.84224 0.12200 0.71580 0.10368 56509.628765 0.000341 0.24958 0.03980 0.97458 0 4.08725 0.29442 3.46841 0.24985 1.02009 0.14514 0.86645 0.12326 56509.629822 0.000715 0.25260 0.02917 0.97976 0 3.71364 0.19305 3.13575 0.16300 0.93807 0.09673 0.79213 0.08168
