About the Operation Request concept to be used during the Solar Orbiter mission
Four format files are used to request operations for RPW:
Figure below gives an example of typical IOR hierarchical tree.
An IOR is an XML file containing a list of sequences sorted by increasing sequence execution time. The sequence execution time is an absolute time in UTC. A sequence is a list of TCs sorted in increasing TC execution times. As illustrated in the figure, the TC execution time values in a sequence must always be relative to the previous TC. Especially, the first TC execution time value in the sequence must always be 00:00:00. It results that a sequence is not absolute time-dependent, whereas a IOR is.
Note that:
Figure below presents the outgoing flow diagram concerning the RPW operation requests. Depending of the type of operations, routine or none routine, there are different ways to submit a request:
