SDP – CSP Pulsar Search and Fast Transient/Single Pulse Data Interface:
I.S1M.SDP_CSP.002
The data exchange between the SDP and the CSP for the pulsar search and
Fast Transient/Single Pulse data interface is fully described in this
section following [AD7] format. Pulsar search and Fast
transient/single pulse data will share a common Data Transport and
Communications protocol (See Par
5.2.3.
to
5.2.7.)
. The communication interface between the CSP and SDP will be
bi-directional although the data flow will be uni-directional (from CSP
to SDP).
The OCLD/SPOCLD are produced by the Non-Imaging Processor component of
the CSP and sent to the SDP for follow-up verification and
identification.
