Due to an error in transcription, the X-ray count rate, flux, and luminosity estimates quoted in ATEL #3592 were in error by a factor of ten. The second paragraph should correctly read:

The inferred count rate of ~0.22 cts ksec^-1 falls below the quoted upper limit of 4 cts ksec^-1 from ATEL #3584 and is not in conflict with that report. Assuming a photon index alpha=2 spectrum, the source X-ray flux would be ~7e-15 erg cm-2 s-1 (0.3-10 keV), and the X-ray luminosity at M101 would be ~4e+37 erg s-1 (0.3-10 keV). This luminosity may be compared to that of the only type Ia SN previously thought to be detected in X-rays, SN 2005ke, which had a >3-sigma detection and estimated L_X = (2 +/- 1)e+38 erg s^-1 in Swift observations over 5--132 days after explosion (Immler et al. 2006, ApJL, 648, L119).

I apologize for any confusion this error may have caused.
