Definitive Data - The complete time history of a particular source
dating back to the beginning of the RXTE mission.
Instrument | 1 mCrab= |
PCA | 1.36 counts/s |
HEXTE | 0.250 counts/s per cluster |
ASM | 0.075 counts/s per camera |
parsec - A parsec is a unit of distance, equal to 3.26 light years.
The Megaparsec, equal to a million parsecs, is another commonly used unit of
astronomical distance.
Quasi-Periodic Oscillations
Pulses of X-rays that are not strictly periodic, but vary slightly from
cycle to cycle are called "quasi-periodic oscillations" or QPOs. This
just means that the pulses are almost, but not quite, periodic.
Real Time Data - The most recent data from RXTE. The Real Time Data
archive logs only the most current two weeks worth.
