Functions#

create_empty_map_dataset_from_irfs(observation)

Create a MapDataset, if energy axes, spatial width or bin size are not given they are determined automatically from the IRFs, but the estimated value cannot exceed the given limits.

create_map_dataset_from_observation(observation)

Create a MapDataset, if energy axes, spatial width or bin size are not given they are determined automatically from the observation IRFs, but the estimated value cannot exceed the given limits.

create_map_dataset_geoms(geom[, ...])

Create map geometries for a MapDataset.

apply_edisp(input_map, edisp)

Apply energy dispersion to map.

split_dataset(dataset, width, margin[, ...])

Split dataset in multiple non-overlapping analysis regions.

Classes#
