10: Dynamic Spectrum: Logical Model
A PSRFITS file is generated for each PST output sub-integration (every 10s).
The PSRFITS files will contain the following:
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.

5.3.1.4.3. Flow Through data types

The raw beam-formed voltage data are defined as the first moments of the electric field, with no temporal or spectral averaging, but optional re-quantisation (e.g. from 8 bits per sample to 2 bits per sample).
A raw data file is generated for each PST output sub-integration (every 10s).
The raw data files will contain the following:
File format: TBD-010
5.3.1.5. Error handling
Failure of the communication link or the receipt of incorrectly formatted data results in an alarm being generated.
5.3.1.6. Variability
This section shows the variability than can be expected and any constraints on specific use cases of the interface or particular aspects of the interface.
Note that parameter values for modes shown in this section are expected or typical values and are provided for information only. This interface does not constrain parameter values unless explicitly stated as a constraint. Actual parameter values will be chosen by Telescope Manager (for each scheduling block and its scans) according to the requirements of the observation and any constraints imposed by components of the telescope [AD6].
Since the beams are independent of each other, a combination of the different observing modes can be used simultaneously. Only one (1) observing mode can be used for a particular Pulsar Timing beam. This also implies that each PST beam can be processed completely independent of the others, and hence all 16 PST beams do not need to be processed by SDP on the same compute node.

5.3.1.6.1. Pulsar Timing Mode Variability

The following Pulsar Timing modes are supported:
These Pulsar Timing modes generate the same data, but with different parameter configurations, see Table 12.
The pulsar timing data cube will have the following axes (SDP_REQ_INT-324):
Table 15 provides the range of parameter values for the 2 Pulsar Timing observing modes as well as a worst case scenario.
