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.
- Parameters:
- observation
Observation Observation containing the IRFs.
- dataset_namestr, optional
Default is None. If None it is determined from the observation ID.
- energy_axis_true
MapAxis, optional True energy axis. Default is None. If None it is determined from the observation IRFs.
- energy_axis
MapAxis, optional Reconstructed energy axis. Default is None. If None it is determined from the observation IRFs.
- energy_bin_per_decade_maxint, optional
Maximal number of bin per decade in energy for the reference dataset
- spatial_width
Quantity, optional Spatial window size. Default is None. If None it is determined from the observation offset max or rad max.
- spatial_width_max
Quantity, optional Maximal spatial width. Default is 12 degree.
- spatial_bin_size
Quantity, optional Pixel size. Default is None. If None it is determined from the observation PSF R68.
- spatial_bin_size_min
Quantity, optional Minimal spatial bin size. Default is 0.01 degree.
- position
SkyCoord, optional Center of the geometry. Default is the observation pointing at mid-observation time.
- frame: str, optional
frame of the coordinate system. Default is “icrs”.
