Get Archived Parameter Segments¶

// Recorded segments for the requested parameter
interface ArchivedParameterSegmentsResponse {
  parameterInfo: ArchivedParameterInfo;
  segments: ArchiveParameterSegmentInfo[];
}

// This message contains information about one parameter in the parameter archive.
// Each (parameter name, raw type, engineering type) is assigned a unique id and all
// the samples are stored with that id.
//
// If an MDB change results in the parameter having a different engineering or raw type,
// a new pid will be allocated.
//
// This is why for the same parameter name, we can have multiple parameter ids.
//
// The parameter archive contains data even for parameters removed from the MDB.

  // Multiple parameters are grouped such that all in one group have
  // the same timestamps. For example: all parameters extracted from
  // one TM packet usually have the same timestamp.
