Pulsar Timing Mode data rate
Pulsar timing data input to SDP will be folded pulse profiles (data
cubes) in a sequence of files, one for each sub-integration.
The data volume per beam is given by: MPT:BEAM =
nsub x (Msubint +
Mmetadata)
Where:
-
Pulsar timing mode data cube size per sub-integration:
Msubint = nbin x nchan
x npol x nbits /8 bytes
-
Pulsar Timing mode metadata (per file): Mmetadata =
50kiB
The data rate per beam is given by: RPT:BEAM =
MPT:BEAM / Tscan bytes/s
Data rates will depend on the number of pulsars observed simultaneously,
as well as the values of the timing parameters. Examples of data volumes
and rates of the 2 Pulsar Timing observing modes using the parameters
from Table 15 are given in Table 16.
