Usage
To use the model, download from the release binaries below a .zip file corresponding to the machine you are running XSPEC in.
- A pre-computed transfer function table is also needed. At time of writing, the release with the latest table model is v0.1.0 (download FITS table here), which is a table for the Kerr metric with
$a \in [-0.998, 0.998]$ and$\theta_\text{obs} \in [ 0^{\circ}, 90^{\circ} ]$ .
Unzip the directory and data. If the data is not in the XSPEC fitting CWD, use the environment variable KLINE_PROF_DATA_DIR to point to the directory containing the table model.
Navigate to the unzipped directory. Within XSPEC, build and load the model:
XSPEC> hmake
XSPEC> lmod klineprofiles .
XSPEC> model kline
Models and model parameters are documented in the README.
Changes
- Remove all panics to avoid nans or otherwise triggering crashes.
- Improve performance by reworking some calculations and binning with a fixed refined grid.
- Adds a kconv10 model.
