# PESummary Configuration Settings¶

Most of the settings used by pesummary are controlled by the pesummary.conf module. This module includes settings like the default matplotlib style properties and default image captions.

Below is the matplotlib style file that is used by default,

```
figure.facecolor : white
lines.solid_capstyle : round
patch.edgecolor : w
patch.force_edgecolor : True
font.size : 22.0
xtick.labelsize : 16.0
ytick.labelsize : 16.0
axes.labelsize : 20.0
axes.titlesize : 20.0
figure.titlesize : 22.0
legend.fontsize : 14.0
font.family: Times New Roman
font.sans-serif: ['Bitstream Vera Sans']
text.usetex: True
mathtext.fontset: stixsans
text.latex.preamble: \renewcommand{\mathdefault}[1][]{}
```

Below are the image captions that are used,

```
# Caption for 1d histogram
caption_1d_histogram = (
"Plot showing the marginalized posterior distribution for {}. The vertical "
"dashed lines show the 90% credible interval. The title gives the median "
"and 90% confidence interval."
)
# Caption for bootstrapped 1d histogram
caption_1d_histogram_bootstrap = (
"Plot showing {} posterior realizations for {}. {} samples were randomly "
"drawn for each test."
)
# Caption for 2d contour plot
caption_2d_contour = (
"Plot showing the 2d posterior distribution for {} and {}. The contours "
"show the 50% and 90% credible intervals."
)
# Caption for autocorrelation plot
caption_autocorrelation = (
"Plot showing the autocorrelation function for {}. This plot is commonly "
"used to check for randomness in the data. An autocorrelation of 1/-1 "
"means that the samples are correlated and 0 means no correlation. The "
"autocorrelation function at a lag of N gives the correlation between "
"the 0th sample and the Nth sample."
)
# Caption for sample evolution plot
caption_sample_evolution = (
"Scatter plot showing the evolution of the collected samples for {}."
)
# Caption for sample evolution plot colored by second variable
caption_sample_evolution_colored = (
caption_sample_evolution[:-1] + " colored by {}."
)
# Caption for preliminary skymap
caption_skymap_preliminary = (
"Plot showing the most likely position of the source. This map has been "
"produced by creating a 2d histogram from the samples of 'ra' and 'dec'. "
"This is a valid approximation near the equator but breaks down near the "
"poles. The 50% and 90% credible intervals are approximate. For true "
"50% and 90% credible intervals a 'ligo.skymap' skymap should be "
"generated."
)
# Caption for ligo.skymap skymap
caption_skymap = (
"Plot showing the most likely position of the source that generated the "
"gravitational wave. We give the 50% and 90% credible intervals. The "
"black region corresponds to the most likely position and light orange "
"least likely."
)
# Caption for strain plot
caption_strain = (
"Plot showing the comparison between the gravitational wave strain "
"measured at the detectors (grey) and the maximum likelihood waveform "
"(orange) for all available detectors. A 30Hz high and 300Hz low pass "
"filter have been applied to the gravitational wave strain."
)
# Caption for frequency domain waveform
caption_frequency_waveform = (
"Plot showing the frequency domain waveform generated from the maximum "
"likelihood samples."
)
# Caption for comparison time domain waveform plot
caption_time_waveform = (
"Plot showing the time domain waveform generated from the maximum "
"likelihood samples."
)
# Caption for psd plot
caption_psd = (
"Plot showing the instrument noise for each detector near the time of "
"detection; the power spectral density is expressed in terms of "
"equivalent gravitational-wave strain amplitude."
)
# Caption for calibration plot
caption_calibration = (
"Plot showing the calibration posteriors (solid lines) and calibration "
"priors (solid band) for amplitude (top) and phase (bottom)."
)
# Caption for default mass1 mass2 classification plot
caption_default_classification_mass_1_mass_2 = (
"Scatter plot showing the individual samples with their classifications "
"over the mass_1 and mass_2 parameter space. The samples have not been "
"reweighted. Green regions correspond to BBHs, blue BNS, orange NSBH and "
"red MassGap."
)
# Caption for population mass1 mass2 classification plot
caption_population_classification_mass_1_mass_2 = (
"Scatter plot showing the individual samples with their classifications "
"over the mass_1 and mass_2 parameter space. The samples have been "
"reweighted to a population prior. Green regions correspond to BBHs, blue "
"BNS, orange NSBH and red MassGap."
)
# Caption for default classification bar plot
caption_default_classification_bar = (
"Bar plot showing the most likely classification of the binary based on "
"the samples."
)
# Caption for population classification bar plot
caption_population_classification_bar = (
"Bar plot showing the most likely classification of the binary based on "
"the samples which have been reweighted to a population prior."
)
# Caption for 2d contour plots
caption_2d_contour = (
"2d contour plot showing the bounded posterior distributions for {} and "
"{}. Each contour shows the 90% credible interval and the posterior "
"distributions are normalized."
)
# Caption for violin plots
caption_violin = (
"Violin plot showing the posterior distributions for {}. The horizontal "
"black lines show the 90% credible intervals."
)
# Caption for spin disk plots
caption_spin_disk = (
"Posterior probability distributions for the dimensionless component spins "
"relative to the normal to the orbital plane, L, marginalized over the "
"azimuthal angles. The bins are constructed linearly in spin magnitude and "
"the cosine of the tilt angles and are assigned equal prior probability."
)
