/* ** ** 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 55859.061287 0.000304 0.11830 0.01814 0.97143 0 10.95019 0.53776 8.23428 0.40280 1.29541 0.18820 0.96160 0.13963 55859.061973 0.000376 0.10712 0.01616 0.98462 0 9.74412 0.45394 7.21692 0.33601 1.04379 0.14977 0.77441 0.11097 55859.062691 0.000341 0.11753 0.01727 0.97458 0 10.09813 0.47830 7.77840 0.36842 1.18687 0.16509 0.91422 0.12714 55859.063365 0.000333 0.10723 0.01618 1.00000 0 10.38730 0.49103 8.02668 0.37945 1.11383 0.15960 0.86196 0.12351 55859.064019 0.000321 0.13621 0.02078 0.96396 0 8.74561 0.45809 6.80695 0.35653 1.19120 0.17067 0.92640 0.13275 55859.064707 0.000367 0.11618 0.01721 1.00000 0 8.98699 0.43424 6.92135 0.33443 1.04408 0.14620 0.80449 0.11265 55859.065509 0.000434 0.08223 0.01258 0.97333 0 10.51511 0.43676 8.07503 0.33540 0.86468 0.12729 0.66466 0.09781 55859.066296 0.000353 0.11066 0.01652 0.99180 0 9.75172 0.46671 7.46893 0.35746 1.07917 0.15262 0.82782 0.11707 55859.067181 0.000532 0.12309 0.01403 0.97283 0 10.44429 0.39202 7.99218 0.29997 1.28561 0.13831 0.98443 0.10590 55859.068081 0.000367 0.11084 0.01675 1.00000 0 9.24826 0.44289 7.05618 0.33792 1.02509 0.14689 0.78051 0.11184 55859.068802 0.000353 0.11703 0.01772 0.98361 0 9.23169 0.45171 7.05768 0.34530 1.08038 0.15481 0.82604 0.11837 55859.069453 0.000298 0.11876 0.01798 0.98058 0 10.80593 0.52949 8.25687 0.40459 1.28328 0.18388 0.98143 0.14063 55859.070118 0.000367 0.10773 0.01665 0.98425 0 9.46260 0.44857 7.19927 0.34127 1.01938 0.14999 0.77633 0.11424 55859.070844 0.000359 0.10806 0.01613 0.98387 0 10.07221 0.46883 7.68228 0.35757 1.08836 0.15435 0.82892 0.11758 55859.071504 0.000301 0.13262 0.01980 0.99038 0 9.75447 0.50402 7.47989 0.38646 1.29368 0.18115 0.99194 0.13890 55859.072352 0.000547 0.12843 0.01450 0.98413 0 9.89497 0.37408 7.54745 0.28533 1.27082 0.13515 0.96892 0.10305
