$ opam update
$ opam install tdm

Usage#

let report kvn_text =
  match Tdm.of_string kvn_text with
  | Ok tdm ->
      Fmt.pr "Participants: %s -> %s@." tdm.metadata.participant_1
        tdm.metadata.participant_2;
      List.iter
        (fun obs ->
          Fmt.pr "  %s: %s = %.6f@." obs.Tdm.epoch obs.Tdm.keyword obs.Tdm.value)
        tdm.observations
  | Error e -> Fmt.epr "%a@." Tdm.pp_error e

API Overview#

  • type t -- Complete TDM: header, metadata, observations
  • type observation -- Epoch + keyword + value (e.g., RANGE, DOPPLER)
  • type metadata -- Participants, modes, path, integration intervals
  • of_string, of_channel, of_file -- Parse KVN format
  • to_string -- Serialize back to KVN format
