Currently the standard asks for the storage of two arrays of lower and upper bin edges. In python: ``` # 50 bins between 1 GeV and 1 PeV bin_edges =...
The units of the background are defined to be : `s^-1 MeV^-1 sr^-1` Everywhere else in the IRFs we use TeV as energy unit.
I think now, we do not make any definitions for the primary hdu. Maybe we should also include at least some header keywords here so a file can be immediately...
The up-to-date celestial reference system is the ICRS, which does not have an equinox. We should require coordinates to be expressen in ICRS and thus drop the equinox keyword.
Hello all, the format currently foresees binned spectral data, the so-called [OGIP](https://gamma-astro-data-formats.readthedocs.io/en/v0.1/ogip/index.html) files, in turn based on [NASA's definition](https://heasarc.gsfc.nasa.gov/docs/heasarc/ofwg/docs/spectra/ogip_92_007/ogip_92_007.html). The OGIP format provides all the input necessary for a classical...
This is an open thread to collect comments and feedback on the proposed formats for [Binned Likelihood Profiles](http://gamma-astro-data-formats.readthedocs.io/en/latest/results/binned_likelihoods/index.html). Since these formats are effectively just SEDs with extra information in each...
For all other IRFs we have `ENERG`, `THETA` first for being consistent it should be `ENERG`, `THETA` and `RAD`.
Hi all, Question: Why is the `OBS_ID` allowed in the [effective areas](https://gamma-astro-data-formats.readthedocs.io/en/latest/irfs/full_enclosure/aeff/index.html), but not in the rest of the IRFs? The reasoning behind adding `OBS_ID` to the effective area is...
The deadtime (or livetime) for CTA is in principle energy dependent (as different telescopes and cameras will have different deadtimes). The question is how to handle that. Fold the deadtime...
The event list extension has an OBS_ID keyword that is currently defined as integer. This comes from the original event list format specification from Karl. It appears however that OGIP...
