Don't forget to activate environment: `source <MY PATH>/venv/bin/activate`

The script number indicates the sequence of execution. The results are placed in `ridge/products/`.

The corresponding shell scripts run Python code with different parameters.

### 01_bgdmodel.py/01_bgdmodel.sh

Calibrates IBIS/ISGRI background model

### 01_crabmodel.py/01_crabmodel.sh

Calibrates Crab detector count rate model.

### 01_crabmodel_plot_poly.py

Plot long-term Crab detector count rate approximated by cubic polynomial function (Fig. B7 in paper).

### 01_crabmodel_plot_sys.py

Plots the normalized distribution of the residuals between the IBIS/ISGRI Crab count rate and the corresponding polynomial fit (Fig. B8 in the paper). The distribution is approximated with a Gaussian function. 

### 02_grxe_resid.py/02_grxe_resid.sh

Calculates difference between detector count rate and that predicted by background model in mCrab units for `GAL` (Galaxy), `BKG` (Extragalactic), or `ALL` (all-sky) regions.

### 02_grxe_resid_plot.py

Plots normalized distribution of the relative residuals of the background model obtained in three energy bands for BKG region (Figs. A5 and A6 in the paper).

### 02_grxe_map.py/03_grxe_map.sh

Makes the map of the residuals in mCrab units (not shown in the paper).

### 03_grxe_flux.py/03_grxe_flux.sh

Estimates flux in regions defined in config.py, and places result in products/Flux, e.g.:

```
cat ../products/Flux/GB.dat
GB A01  25.00   60.00 154.886019 3.087652
GB A02  60.00   80.00 96.472798 9.218161
GB A03  80.00  200.00 102.207302 13.291950
```
where GB means Galactic Bulge region (see Table 1 in the paper).

### 03_grxe_galprof.py/03_grxe_galprof.sh and 03_grxe_galprof_plot.py

Makes Galactic longitude profile and plots it.

### 03_grxe_spec.py

Extract spectrum of selected sky region, e.g.:

```./03_grxe_spec.py GB``` or  ```./03_grxe_spec.py L+20```

If you do not specify the sky region, the script makes spectra for all regions.

Sky regions are defined in ```config.py```.

Spectra are stored in `../products/Spectra`.

To load the spectrum, e.g. Galactic Bulge, do the following steps:

```
cd ../products/Spectra
cp ../../models/xspec/* .
```

Then data and spectral models can be loaded by the following scripts in `xspec`:

```
xspec

@load_gb_cutoffpl.xcm
@load_gb_polar.xcm

@load_l+20_cutoffpl.xcm
@load_l+20_polar.xcm

@load_l-20_cutoffpl.xcm
@load_l-20_polar.xcm
```

### 03_grxe_syserr.py/03_plot_bkg.py/03_plot_skyreg.py

Prints statistics and plots distribution of residuals for extragalactic data, and for selected sky regions.
