milliCrab
One thousandth of the intensity of the Crab nebula. X-ray astronomers use this unit when comparing observations from different X-ray detectors on different instruments. On RXTE, for example:
| Instrument | 1 mCrab= |
| PCA | 2.786 counts/s/pcu |
| HEXTE | 0.250 counts/s per cluster |
| ASM | 0.075 counts/s per camera |
