Use float32 dtype for maps

1

Most of the memory and CPU time in Gammapy is related to maps. Currently we have a mix of 32 and 64 bit float dtype for maps. I suggest we...

cli_download_tutorials options

4

The options (`src`, `out`, `release` and `modetutorials`) on `cli_download_tutorials` currently aren't processed, they are ignored: https://github.com/gammapy/gammapy/blob/fc4603ec58bdbd25386c5c5eb2a9664cce93769b/gammapy/scripts/download.py#L86 We should either implement those options (probably by storing them on the click context...

Float and int data types in gammapy.maps

1

This is an issue labeled "question", under the 1.0 milestone to discuss how we should handle different float and int data types in `gammapy.maps`, to follow up on the discussion...

Location of I/O code in Gammapy

7

@MaxNoe in https://github.com/gammapy/gammapy/issues/1265#issuecomment-365260031 made this comment that I think we should discuss separately (i.e. in this new issue): > I think that core functionality must be completely agnostic of file...

Coding pattern to handle scalars in functions

1

Numpy behaves nicely wrt. scalars and arrays, i.e. when given a scalar it returns a scalar: ```python >>> import numpy as np >>> np.sin(42) -0.9165215479156338 >>> np.sin([42]) array([-0.91652155]) >>> np.sin([[42]])...

Input validation and better errors from map initialisers

6

@robertazanin and I were very confused for a while by this (actually in a more complex setting, here just a minimal example): ```python >>> from gammapy.maps import Map, WcsNDMap >>>...

Make a tutorial notebook for a spectral analysis with obs grouping

6

This is a reminder issue to follow up on #1575 . I think we should change this docs page: https://github.com/cdeil/gammapy/blob/75b9321d3f385885483e44ef49278ac78545cad8/docs/data/obs_group.rst to a tutorial notebook, and actually show a working example...

Gammapy validation: joint Crab analysis

4

As part of the Gammapy validation effort while preparing v1.0, we should try to reproduce the joint likelihood spectral analysis for the Crab nebula that we did with Gammapy v0.9...

Gammapy validation: HESS DL3 DR1

2

As part of the Gammapy validation effort while preparing v1.0, we should script some of the H.E.S.S. data level 3, data release 1 analyses for validation. Note that large parts...

Gammapy validation: Fermi-LAT 3FHL

1

As part of the Gammapy validation effort while preparing v1.0, we should try to reproduce some of the Fermi-LAT 3FHL high-energy catalog analysis results. A task description and references are...
