peaks_to_pixels

anri.fwd.peaks_to_pixels(centroid, cov, amplitude, bins, window_size)

Vectorized version of peak_to_pixels. Takes similar arguments as peak_to_pixels but with additional array axes over which peak_to_pixels is mapped.

Original documentation:

Get N*(window_size,) image of normalised pixel intensities around centroid in N dimensions.

This can be vectorised over centroids, see peaks_to_pixels().

Parameters:

• centroid (Array) – [N] Coordinate of peak centroid in N dimensions

• cov (Array) – [3, N] output covariance matrix from anri.fwd.propagate_cov_box() or anri.fwd.propagate_cov_scan()

• amplitude (float) – Total integrated amplitude of the peak

• bins (tuple[Array]) – The bin centres for each dimension ( e.g (sc, fc, omega, [dty]) )

• window_size (int) – The window size to evaluate pixel intensities

Returns:

• intensities_dense (jax.Array) – [N*(window_size,)] Dense image of intensities around the centroid

• starts (jax.Array) – [N] Start indices (of bins) to the intensity image
