DESCRIPTION:Speakers: Irmak Aytekin (University of Toronto)\nImaging Fouri
 er-transform spectrographs (IFTS) such as SITELLE record spectral informat
 ion by scanning a Michelson interferometer mirror and are reduced with the
  ORBS pipeline\, which assumes conventional camera-style\, frame-based exp
 osures. We are developing a laboratory prototype IFTS built around Microwa
 ve Kinetic Inductance Detectors (MKIDs): energy-resolving\, photon-countin
 g sensors that read out continuously rather than in discrete frames. This 
 mismatch between MKID's continuous photon stream and ORBS's frame-based in
 put format is the central obstacle to reusing existing SITELLE-heritage re
 duction software for the new instrument.\n\nWe present the Synchronisation
  Gate\, a software module that reconciles the two data formats by binning 
 the continuous MKID photon stream along two axes simultaneously: mirror po
 sition\, using timestamps from the interferometer's actuator log to isolat
 e stable-alignment windows\, and photon energy\, using each photon's intri
 nsic energy resolution. An efficient binary-search-based algorithm convert
 s the raw photon table into a (step\, energy bin\, y\, x) frame array that
  ORBS can ingest directly. Because MKIDs resolve photon energy natively\, 
 this also enables an "N-cube" strategy: splitting one photon stream into N
  independent energy-sliced datacubes\, each reduced in parallel through a 
 modified ORBS roadmap that bypasses SITELLE's two-camera-specific calibrat
 ion steps.\n\nThe gate has been implemented and integrated into the lab's 
 MKID data pipeline and validated against synthetic photon-stream data. Rem
 aining work includes full end-to-end validation on real detector data and 
 flux calibration without on-sky standards. This work demonstrates a practi
 cal path for extending mature astronomical spectral-reduction software to 
 a fundamentally different detector technology.\n\nhttps://nyx.physics.mcgi
