Methods

Recipe BC Methods. A Method names a technique abstractly (ISA-88 General Recipe layer). Two binding fields, distinct purposes: needed_families lists the Equipment Families the technique requires hardware-compat-wise; capability_id binds to a Recipe Capability template that declares the operations contract (required affordances, parameter schema, executor shape). Methods are cross-facility vocabulary, not bound to any Site. See Model for the aggregate shape.

Method	Capability	Needed families	Purpose
motor_homing	maintenance	RotaryStage, LinearStage	Reference-position seek for one or more motorized Devices; produces motors with encoders zeroed and ready for absolute-coordinate moves
resolution_alignment	alignment	LinearStage, Camera, Scintillator	The resolution step in the rotation-axis alignment chain; iterative focus-Z peak search on a mounted resolution target
focus_alignment	alignment	LinearStage, Camera, Scintillator	The focus step in the rotation-axis alignment chain; iterative Sample-Z peak search for depth-of-focus on the mounted sample
center_alignment	alignment	RotaryStage, LinearStage, Camera, Scintillator	The center step in the rotation-axis alignment chain; iterative 0°/180° convergence on the calibrated rotation-axis pixel position
roll_alignment	alignment	RotaryStage, LinearStage, Camera, Scintillator	The roll step in the rotation-axis alignment chain; iterative 0°/180° Y-delta correction to make the rotation axis perpendicular to the camera Y axis
pitch_alignment	alignment	RotaryStage, LinearStage, Camera, Scintillator	The pitch step in the rotation-axis alignment chain; iterative 0°/180° sharpness-delta correction to make the rotation axis perpendicular to the beam direction
first_light	acquisition	Shutter, Camera, Scintillator	The canonical commissioning milestone; dark + first-light + safe-state frame ceremony confirming beam reaches the detector
dark_baseline	acquisition	Shutter, Camera, Scintillator	Dark-frame stack acquisition + pixel-wise baseline computation, producing a Dataset for reconstruction subtraction
flat_baseline	acquisition	Shutter, Camera, Scintillator	Flat-field stack acquisition (shutter open, no sample) + pixel-wise baseline computation, producing a Dataset for reconstruction division
hexapod_reboot	maintenance	Hexapod	Recovery routine for a stuck hexapod controller: IOC stop, PDU power-cycle, IOC start, EPICS enable check
tomography	tomography	RotaryStage, LinearStage, Camera, Scintillator	The canonical proposal-driven imaging routine; runs as a Run aggregate that produces an H5 projection-stack Dataset (operator-supplied exposure_ms + n_projections + angle_range_deg validated against the Method's parameters_schema)
alignment_calibration	calibration	RotaryStage, LinearStage, Camera, Scintillator	Pre-step of the alignment chain; measures motor-sensitivity constants empirically (bump axis by known delta, observe sphere centroid shift, compute K = shift/bump) — patches the existing chain's "K values appear from nowhere" gap
streaming_tomography	tomography	RotaryStage, LinearStage, Camera, Scintillator	TomoScanStream + tomoStream live-reconstruction; supports mid-flight adjust_run steering on operator-observed reco quality (autonomous-CT pathway)
continuous_rotation_tomography	tomography	RotaryStage, LinearStage, Camera, Scintillator	N back-to-back rotation Runs sharing one Plan + one Subject under a Campaign(intent=Series); one TomoScan call yields N child Runs
mosaic_tomography	tomography	RotaryStage, LinearStage, Camera, Scintillator	Tiled lateral-translation tomography for samples larger than the field of view; multiple Runs stitched by post-processing
