Fermipy tools to improve a model¶
In this notebook I show how to use Fermipy in order to improve the model for an roi. This is done in a ROI centered on M31 (Andromeda Galaxy).
I report below the configuration file that we are going to use.
We first import a few packages:
In [30]:
%matplotlib inline
import os
import numpy as np
from fermipy.gtanalysis import GTAnalysis
from fermipy.plotting import ROIPlotter, SEDPlotter
import matplotlib.pyplot as plt
import matplotlib
from IPython.display import Image
from math import *
We can save in the folder this configuration file making
In [13]:
if os.path.isfile('../data/M31_data.tar.gz'):
!tar xzf ../data/M31_data.tar.gz
else:
!curl -OL https://raw.githubusercontent.com/fermiPy/fermipy-extras/master/data/M31_data.tar.gz
!tar xzf M31_data.tar.gz

As we can see there are large residuals in the TS map and in the residuals map. Therefore, we certainly have to improve our model.

Source Localization¶
The first thing to do in order to improve the model is to relocalize the sources of your model. In particular in our case where we have 3FGL source this is particularly requested.
The localize() method can be used to spatially localize a source. Localization is performed by scanning the likelihood surface in source position in a local patch around the nominal source position. The fit to the source position proceeds in two iterations: TS Map Scan: Obtain a first estimate of the source position by generating a likelihood map of the region using the tsmap method. In this step all background parameters are fixed to their nominal values. The size of the search region used for this step is set with the dtheta_max parameter. Likelihood Scan: Refine the position of the source by performing a scan of the likelihood surface in a box centered on the best-fit position found in the first iteration. The size of the search region is set to encompass the 99% positional uncertainty contour. This method uses a full likelihood fit at each point in the likelihood scan and will re-fit all free parameters of the model. If a peak is found in the search region and the positional fit succeeds, the method will update the position of the source in the model to the new best-fit position.
We will localize all the sources in the model. We include a function to calculate the angular distance from two directions in the sky.

Source Extension¶
Now we will run the extension to all sources using gta.extension.
In [43]:
help(gta.extension)
Help on method extension in module fermipy.extension:
extension(self, name, **kwargs) method of fermipy.gtanalysis.GTAnalysis instance
Test this source for spatial extension with the likelihood
ratio method (TS_ext). This method will substitute an
extended spatial model for the given source and perform a
one-dimensional scan of the spatial extension parameter over
the range specified with the width parameters. The 1-D
profile likelihood is then used to compute the best-fit value,
upper limit, and TS for extension. The nuisance parameters
that will be simultaneously fit when performing the spatial
scan can be controlled with the ``fix_shape``,
``free_background``, and ``free_radius`` options. By default
the position of the source will be fixed to its current
position. A simultaneous fit to position and extension can be
performed by setting ``fit_position`` to True.
Parameters
----------
name : str
Source name.
fit_ebin : bool
Perform a fit for the angular extension in each analysis
energy bin. (default : False)
fit_position : bool
Perform a simultaneous fit to the source position and
extension. (default : False)
fix_shape : bool
Fix spectral shape parameters of the source of interest. If
True then only the normalization parameter will be fit.
(default : False)
free_background : bool
Leave background parameters free when performing the fit. If
True then any parameters that are currently free in the
model will be fit simultaneously with the source of
interest. (default : False)
free_radius : float
Free normalizations of background sources within this
angular distance in degrees from the source of interest. If
None then no sources will be freed. (default : None)
make_plots : bool
Generate diagnostic plots. (default : False)
make_tsmap : bool
Make a TS map for the source of interest. (default : True)
psf_scale_fn : tuple
Tuple of two vectors (logE,f) defining an energy-dependent
PSF scaling function that will be applied when building
spatial models for the source of interest. The tuple
(logE,f) defines the fractional corrections f at the
sequence of energies logE = log10(E/MeV) where f=0
corresponds to no correction. The correction function f(E)
is evaluated by linearly interpolating the fractional
correction factors f in log(E). The corrected PSF is given
by P'(x;E) = P(x/(1+f(E));E) where x is the angular
separation. (default : None)
save_model_map : bool
Save model counts cubes for the best-fit model of extension.
(default : False)
spatial_model : str
Spatial model that will be used to test the sourceextension.
The spatial scale parameter of the model will be set such
that the 68% containment radius of the model is equal to the
width parameter. (default : RadialGaussian)
sqrt_ts_threshold : float
Threshold on sqrt(TS_ext) that will be applied when
``update`` is True. If None then nothreshold is applied.
(default : None)
update : bool
Update this source with the best-fit model for spatial
extension if TS_ext > ``tsext_threshold``. (default : False)
width : list
Sequence of values in degrees for the likelihood scan over
spatial extension (68% containment radius). If this
argument is None then the scan points will be determined
from width_min/width_max/width_nstep. (default : None)
width_max : float
Maximum value in degrees for the likelihood scan over
spatial extent. (default : 1.0)
width_min : float
Minimum value in degrees for the likelihood scan over
spatial extent. (default : 0.01)
width_nstep : int
Number of scan points between width_min and width_max. Scan
points will be spaced evenly on a logarithmic scale between
`width_min` and `width_max`. (default : 21)
write_fits : bool
Write the output to a FITS file. (default : True)
write_npy : bool
Write the output dictionary to a numpy file. (default :
True)
optimizer : dict
Dictionary that overrides the default optimizer settings.
Returns
-------
extension : dict
Dictionary containing results of the extension analysis. The same
dictionary is also saved to the dictionary of this source under
'extension'.
We use the option update=True and sqrt_ts_threshold=3.0 that will update the spatial template of the source if the TS of extension larger than 9.

Find new sources¶
After we have renormalized the 3FGL sources and we have found if the sources are extended, we will try to find new sources with the tool find_sources().
find_sources() is an iterative source-finding algorithm that uses peak detection on a TS map to find new source candidates. The procedure for adding new sources at each iteration is as follows: Generate a TS map for the test source model defined with the model argument. Identify peaks with sqrt(TS) > sqrt_ts_threshold and an angular distance of at least min_separation from a higher amplitude peak in the map. Order the peaks by TS and add a source at each peak starting from the highest TS peak. Set the source position by fitting a 2D parabola to the log-likelihood surface around the peak maximum. After adding each source, re-fit its spectral parameters. Add sources at the N highest peaks up to N = sources_per_iter. Source finding is repeated up to max_iter iterations or until no peaks are found in a given iteration. Sources found by the method are added to the model and given designations PS JXXXX.X+XXXX according to their position in celestial coordinates.
