  1. From AtlasID to ROBID

  2. Atlas ID • StName/StEta/StPhi/DoubletR/DoubletZ/DoubletPhi/GasGap/MeasuresPhi/strip • I primi 4 identificano la collezione offline (da utilizzare per ottenere l’hashID) • St. Eta ( da -8 a +8) • Serve solo il segno per capire il Side A (+) e side C (-) • St. Name (BOL,BML,BOS,BMS,etc..) • St. Phi (da 1 a 8) • DoubletPhi (equivalente a HV RO sulle stazioni a muoni) • Servono per stabilire il settore di trigger e quindi il ROD • Doublet R è ininfluente nella selezione del ROB ID

  3. Settori di Trigger e Station Phi • View from side C to Side A Station Phi = 2 Station Phi = 1

  4. Atlas ID

  5. Atlas ID • La tabella ha 64 entries • Possible o una lookup-table o un algoritmo • Utilizzando solo StName/StEta/StPhi dunque, si possono ottenere 2 ROBID differenti. • Solo utilizzando anche dblPhi si ottiene un ROBID univoco.

  6. Error Handling in Online RPCDecoding

  7. Possible data fragment errors • NO_RX_FRAG • No Rx frag inside ROD frag. Skipping event • BAD_RX_FRAG • Rx frag is corrupted. Skipping rx frag • NO_PAD_FRAG • No PAD frag inside Rx frag. Skipping • BAD_PAD_FRAG • PAD frag is corrupted. Skipping pad frag • NO_CM_FRAG • No CM frag inside PAD frag. Skipping • BAD_CM_FRAG • CM frag is corrupted. Skipping CM frag

  8. Still missing • Too long events are truncated by ROD and flagged. • No reaction by Decoder, also good subfragments rejected. • No check of error words inside the fragments footer. • Only stored in the containers without any reaction.
