/* ** ** 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 58821.121351 0.000269 0.15228 0.01182 0.98925 0 30.83657 0.86226 28.23713 0.78957 4.69592 0.34003 4.29819 0.31121 58821.121926 0.000307 0.13360 0.01006 1.00000 0 31.50473 0.82085 28.58956 0.74489 4.20903 0.29736 3.81951 0.26982 58821.122496 0.000263 0.15646 0.01192 1.00000 0 31.41058 0.88514 28.59100 0.80572 4.91454 0.34773 4.47324 0.31645 58821.123040 0.000281 0.14804 0.01152 1.00000 0 30.00750 0.83892 27.39848 0.76598 4.44226 0.32246 4.05598 0.29445 58821.123613 0.000292 0.14517 0.01112 1.00000 0 29.95507 0.82323 27.22602 0.74827 4.34864 0.31081 3.95101 0.28235 58821.124166 0.000260 0.16352 0.01262 0.98889 0 30.09861 0.87662 27.39906 0.79798 4.92159 0.35168 4.48373 0.32042 58821.124719 0.000292 0.13159 0.01013 1.00000 0 32.45731 0.84805 29.75278 0.77738 4.27110 0.30925 3.91518 0.28348 58821.125312 0.000301 0.13649 0.01043 0.99038 0 30.97503 0.82148 28.21487 0.74822 4.22788 0.30297 3.85484 0.27618 58821.125876 0.000263 0.15576 0.01217 1.00000 0 30.44397 0.87144 27.91175 0.79895 4.74207 0.34471 4.34755 0.31603 58821.126432 0.000292 0.13547 0.01039 1.00000 0 31.88734 0.84703 29.00316 0.77036 4.31990 0.31075 3.93310 0.28292 58821.126999 0.000275 0.15198 0.01170 0.98947 0 30.67766 0.86013 27.78755 0.77913 4.66225 0.33412 4.22392 0.30262 58821.127531 0.000258 0.16076 0.01255 1.00000 0 30.58964 0.89145 27.63991 0.80550 4.91746 0.35603 4.44307 0.32171 58821.128095 0.000307 0.13380 0.01020 1.00000 0 30.86070 0.80976 28.28984 0.74230 4.12930 0.29550 3.78537 0.27089 58821.128671 0.000269 0.15026 0.01160 1.00000 0 30.99974 0.86641 28.42674 0.79450 4.65806 0.33506 4.27143 0.30725 58821.129201 0.000260 0.15693 0.01203 1.00000 0 30.80672 0.87980 28.24133 0.80654 4.83436 0.34409 4.43175 0.31544 58821.129776 0.000315 0.12932 0.00966 0.99083 0 32.11229 0.81771 29.11421 0.74129 4.15267 0.29148 3.76553 0.26429 58821.130416 0.000324 0.13036 0.00990 1.00000 0 30.30504 0.79002 27.46746 0.71591 3.95065 0.28163 3.58085 0.25525 58821.131009 0.000269 0.15347 0.01199 0.97849 0 30.93410 0.86978 28.16966 0.79200 4.74761 0.34604 4.32554 0.31526 58821.131608 0.000330 0.14857 0.01039 1.00000 0 31.39507 0.78602 28.55855 0.71496 4.66435 0.30441 4.24193 0.27689
