Band (channel) table

Band (channel) table

Usage

at_bands(x, call = rlang::caller_env())

Arguments

x

An annot_image.

call

The calling environment, for error reporting.

Value

A tibble::tibble with one row per band and the columns:

index

Band index, 1-based (integer).

name

Band name (character); a default "Band k" when unnamed.

wavelength

Centre wavelength (double); NA when not spectral or unknown for that band. Never interpolated.

unit

Wavelength unit (character); NA when not spectral.

fwhm

Full width at half maximum in the wavelength unit (double); NA when the source does not declare it.

order

Position of the band in file/manifest order (integer).

wavelength_status

"ok", "missing", "duplicate" or "non_numeric" (character).

Always has at_n_bands(x) rows. The first four columns are unchanged from annotatR 0.1; the remaining columns were added in 0.2.0.
