Count rates vary about a mean value, and counts must be averaged over time to obtain a reasonable estimate of the mean.

Porosity is derived from the ratio of count rates at these two detectors rather than from count rates at a single detector.

NbN devices have demonstrated device detection efficiencies as high as 67 % at 1064 nm wavelength with count rates in the hundreds of MHz.

Despite its shortcomings, the concept of a spike-count rate code is widely used not only in experiments, but also in models of neural networks.
15.
With the time-to-first-count method, effective count rates of 10 5 counts per second are achievable, two orders of magnitude larger than the normal effective limit.
16.
Burst data consist of either 16 s of 8-ms resolution count rates or 64 s of 32-ms count rates from the sum of the 2 detectors.

Both the photon count rate and the photon energy are redshifted . ( See K correction for more details on the photometric consequences of redshift .)
19.
A consequence of this is that ion chamber instruments are usually preferred for higher count rates, however a modern external quenching technique can extend this upper limit considerably.

IXO optics and instrumentation will provide up to 100-fold increase in effective area for high resolution spectroscopy, deep spectral, and microsecond spectroscopic timing with high count rate capability.
