getframes 2.1.0

[2.1.0] - 2026-07-19

Added

• Five scientific-camera presets used by the Keck tip/tilt and low-bandwidth WFS
  detector trade example: KURO 1200B, Prime 95B, Marana 4.2B-11, QHY530 Pro II,
  and Aries 6504 Pro. All five now include a wavelength-resolved qe_curve:
  Marana and Aries from Andor's/Gpixel's published data (the Aries
  QE x fill factor trace is digitized from Gpixel's graph); KURO 1200B,
  Prime 95B, and QHY530 Pro II are digitized from published manufacturer QE
  plots.
• A quantum_efficiency override on Camera.expose_series, matching
  Camera.expose and supporting pre-integrated spectral electron-rate series.
• A Keck/SciMeasure Little Joe CCD39 preset with the manufacturer CCD39-01
  standard-AR/no-window spectral-response curve.
• getframes.analysis.matched_filter_centroid, a background-insensitive
  cross-correlation centroid with sub-pixel peak refinement.
• Frame.binned(factor, method=...), post-read digital binning of a frame into
  factor x factor super-pixels (sum or mean).
• CameraConfig.supported_binnings and CameraConfig.binning_method — binning is
  now a first-class config parameter. The Keck-trade presets set these directly and
  drop the extra.detector_modes per-binning tables; cameras with more than one
  read-noise operating point keep a slim extra.read_modes list instead.
• Native pixel binning in the signal chain: Camera.expose, Camera.expose_series,
  and noise.simulate_frame accept binning and binning_mode. "digital"
  (post-read, the default) reads each native pixel with its own read noise then sums,
  so binned read noise grows as binning; "on_chip" (pre-read charge-domain /
  hardware binning) sums the charge before the amplifier, so a single read noise is
  applied per super-pixel. Exposed noise.block_sum for the super-pixel summation.
• getframes.analysis.centroid now accepts a per-pixel array background (e.g. a
  master sky+dark frame) and an optional threshold (scalar or per-pixel noise
  map), making it a calibrated thresholded centre-of-gravity estimator suitable
  for a real-time controller. Both additions are backwards compatible.
• A Keck LGS tip/tilt and low-bandwidth wavefront-sensor detector trade-study
  example, including physically sampled AO/sub-aperture PSFs, complete detector
  Monte Carlo simulations, blackbody NGS weighting of each camera's QE curve
  (--ngs-teff), the 600–950 nm TTS/LBWFS arm bandpass folded into the zero-point
  bands, Monte Carlo standard errors on every point, a per-camera closed-loop
  cadence optimisation (a physical a·f + b·f² noise model fitted to the Monte
  Carlo data, saturation-aware, against a Tyler tilt-lag disturbance model), and
  a best/worst-performer frame gallery figure beside the trade curves.

Fixed

• Type-checking compatibility with newer NumPy (2.2): tightened stub types for
  _stamp_bounds/_radial_grid shape arguments, pinned float64 on a few
  np.linspace constructions, and dropped now-unused type: ignore comments
  around the trapz/trapezoid shim. No behavioural change.
