simulate_sparse

anri.io.simulate_sparse(path, entries, hkls, F2, geom, omega, dty, det_shape, cut=1, transmission=None, omega_motor='rot_center', dty_motor='dty', window=(3, 7, 7), batch=65536, max_frames=None)

Render every dty row of a scan and write the sparse pixels file, one row at a time.

Parameters:

• path (str) – Output HDF5 file; must not exist

• entries (dict) – See anri.fwd.render_row(), for a single phase

• hkls (ndarray) – See anri.fwd.render_row(), for a single phase

• F2 (ndarray) – See anri.fwd.render_row(), for a single phase

• geom (dict) – See anri.fwd.render_row(), for a single phase

• omega (ndarray) – [n_rows, n_frames] motor positions, e.g. from motor_grid() or an ImageD11 DataSet

• dty (ndarray) – [n_rows, n_frames] motor positions, e.g. from motor_grid() or an ImageD11 DataSet

• det_shape (tuple[int, int]) – (n_slow, n_fast)

• cut (float, default: 1) – Keep counts strictly above this

• transmission (ndarray | None, default: None) – Optional [n_rows, n_frames] transmission factor per frame

• omega_motor (str, default: 'rot_center') – Motor names written to the file

• dty_motor (str, default: 'dty') – Motor names written to the file

• window (tuple[int, int, int], default: (3, 7, 7)) – Passed on to anri.fwd.render_row()

• batch (int, default: 65536) – Passed on to anri.fwd.render_row()

• max_frames (int | None, default: None) – Passed on to anri.fwd.render_row()

Returns:

stats (dict) – Per row: “n_peaks” rendered, “n_pixels” written, and the minimum window “captured” fraction
