http://ipta.phys.wvu.edu/files/student-week-2024/PulsarTimingII_tempo2.pdf Tempo is a computer program to analyze radio observations of pulsars. Once enough observations are available, Tempo can deduce the pulsar rotation rate and phase, astrometric position and rates of change, and parameters of binary systems, by fitting models to pulse times of arrival measured at one or more terrestrial observatories. This is a non-trivial procedure because much larger effects must be removed before the detailed fit can be performed. These include:
WebDec 1, 2013 · This is most commonly carried out using the tempo, 1 and more recently, tempo 2 pulsar timing packages (Hobbs, Edwards & Manchester 2006; Edwards, Hobbs, & Manchester 2006; Hobbs et al. 2009). tempo 2 uses an initial guess of the timing model to generate a set of pre-fitting residuals. A Fisher-matrix approximation to the timing model ... WebTempo analyzes pulsar timing data. Pulse times of arrival (TOAs), pulsar model parameters, and coded instructions are read from one or more input files. The TOAs are …
WebPulsar Timing Variations. Pulsars are weird stellar objects that emit regular pulses of radio waves, often quite fast. They are neutron stars—the rapidly rotating, ultra-dense leftover … WebThe primary mode of use for TEMPO takes a par file which specifies a model for a given pulsar and a tim file that contains actual times of arrival for the pulsar, then calculates …
