dedisp!(output,source,plan)

Dedisperses dynamic spectra source in-place into output according to the dedispersion plan plan.

• source has dimensions time samples x frequency channels
• output has dimensions starting time samples x DM trials
• plan has dimensions frequency channels x DM trials

dedisp!(output, source, chunked_plan)

Identical to dedisp! except operates on chunked plans. Returned is the reduced output.

plan_chunked_dedisp(freqs, f_max, dms, δt, n_chunk)

(GPU-Only) Identical to plan_dedisp except chunks the frequencies by n_chunk.

plan_dedisp(freqs, f_max, dms, δt)

Create a dedispersion plan for that covers pulses dispersed over freqs with a maximum of f_max in MHz over all possible DMs in dms with source time resolution δt

standardize(A)

Transform matrix A into units of signal to noise ratio along optional dimension dim, defaulting to the first dimension.

Δt(f_min, f_max, DM, δt)

Given two frequency bounds, f_min and f_max in MHz, get the time shift in samples for a dispersed pulse of dispersion measure DM.

Δt(f_min, f_max, DM)

Given two frequency bounds, f_min and f_max in MHz, get the time shift in seconds for a dispersed pulse of dispersion measure DM.
