7: Pulsar Timing: Conceptual Model
8: Pulsar Timing: Logical Model
A PSRFITS file is generated for each PST output sub-integration
(typically every 10s, 1 - 60s range).
The PSRFITS files will contain the following:
-
Metadata: Pulsar Timing Metadata shall be stored in the PSRFITS data
file as keywords [AD5]. (SDP_REQ_INT-66)
-
Data cube metadata: Diagnostic and heuristic metadata
-
Data cube: Folded pulse profile
The PSRFITS file may also include optional extensions (e.g. digitiser
statistics) as per the standard [AD5].
File format: PSRFITS [AD5]
The PSRFITS version number is not specified in this ICD because it is
defined in the header of the file.
5.3.1.4.2.
Dynamic Spectrum data types
The dynamic spectra data are defined as the second moments of
the electric field (e.g. the Stokes parameters), averaged as a function
of time, radio frequency and optionally, polarisation. The data cube may
be stored in multiple PSRFITS files, with many time samples per file
(e.g 10 seconds).
