In the bottom right panel, we show the trace of each 16 walkers for 500 runs (the chain described previsouly). For the first 100 runs, the parameter evolve towards a solution (can be viewed as a fitting step). Then they explore the local minimum for 400 runs which will be used to estimate the parameters correlations and errors. The choice of the Nburn value (when walkers have reached a stationary stage) can be done by eye but you can also look at the autocorrelation time.

Phase computation for pulsar using PINT

This notebook has been done for the following version of Gammapy and PINT:

-

Gammapy version : 1.0.1

-

PINT version : 0.9.5

+

Gammapy version : 1.2

PINT version : 1.0

This notebook shows how to compute and add the phase information into the events files of pulsar observations. This step is needed to perform the pulsar analysis with Gammapy and should be the first step in the high level analysis. For the pulsar analysis we need two ingredients:

  1. The time of arrivals (TOAs). These times should have very high precision due to the common fast periods of pulsars. Usually these times are already stored in the EventList. For the computation of pulsar timing, times must be corrected in order to be referenced in the Solar System barycenter (SSB) because this system can nearly be regarded as an inertial reference frame with respect to the pulsar.

    2. -

  2. The model of rotation of the pulsar, also known as ephemeris, at the epoch of the observations. These ephemerides are stored in an specific format and saved as .par files and contain informations on the periods, derivatives of the periods, coordinates, glitches, etc.

  3. The model of rotation of the pulsar, also known as ephemeris, at the epoch of the observations. These ephemerides are stored in a specific format and saved as .par files which contain the periods, derivatives of the periods, coordinates, glitches, etc.

For the following steps of this tutorial, we need the original EventLists from the DL3 files, and a model in .par format.

The main software that we will use to make the barycentric corrections and the phase-folding to the model is the PINT python library, Luo J., Ransom S. et al., 2021, ASCL. For more information about this package, see PINT documentation.

2. Phase-folding with PINT for one observation

2.1 An ephemeris file from Fermi-LAT data.

-

In order to compute the phases of a pulsar, one needs an ephemeris file, usually store as a .par file.

+

In order to compute the phases of a pulsar, one needs an ephemeris file, typically stored as a .par file.

In the following, we will use an ephemeris file for the Crab provided by Fermi-LAT, see Kerr, M.; Ray, P. S.; et al; 2015. This ephemeris file for the Crab pulsar can be found alongside other pulsar ephemeris files at this confluence page.

-

However, be aware that most of these ephemeris files are not up-to-date. Therefore they could give bad results on the phase computation. In particular, one should always checked that the MJD of the observations one wants to phased lies between the STARTand FINISHentry of the ephemeris file.

+

However, it is important to note that many of the ephemeris files are not up-to-date. Therefore, they could give bad results on the phase computation. In particular, you should always check that the MJD of the observations one wants to phase lies between the START and FINISH entries of the ephemeris file (see next section).

[13]:
 
# Path to the ephemeris file
-ephemeris_file = "./0534+2200_ApJ_708_1254_2010.par"
+ephemeris_file = "0534+2200_ApJ_708_1254_2010.par"
-

Note that sometimes one needs to change some of the parameters of the ephemeris file that are not used in gamma-ray astronomy by hand. For instance, here we have removed the ‘JUMP’ line since it does not have any effect in our computation and raise an error in PINT. The ephemeris file provided with this notebook does not have this line.

+

Note that Fermi-LAT ephemeris files are created primarily by and for Tempo2. Most of the time, using such ephemeris file with PINT will not raise any issues. However, in a few cases, PINT does not support features from Tempo2.

+

In our case, an error occurs when using the ephemeris file with PINT. This is due to the JUMP line. To proceed, simply comment out the line (with #) or remove it. Note that this line is not important for the gamma-ray instruments, so it is acceptable to disregard it.

2.2 Computing pulsar phasesPINT documentation

-

Now we can compute the phases. For that, we define a list of TOA objects that are the main object of PINT.

+

There are multiple parameters such as the name of the source, the frequencies of rotation and its derivatives (F0,F1,F2), the dispersion measure, etc. Check the PINT documentation for a list of additional parameters. To obtain the complete set of parameters from the ephemeris file, one can simply print the model: print(model)

+

As mentioned previously, we should ensure the time of the observation lies within the ephemeris time definition. In our example, we only have one run, so we can check that manually:

[15]:
+
print(
+    f"Ephemeris time definition:\n{model.START.value} - {model.FINISH.value}"
+)
+print(
+    f"Observation time definition:\n{observation.tstart} - {observation.tstop}"
+)
+
+
+
+
+
+
+
+
+Ephemeris time definition:
+54686.1526259 - 56583.1591704
+Observation time definition:
+56569.18112772242 - 56569.19487901596
+
+
+

If you have several observations that are sorted by time, you can manually check for the start time of the first observation and the stop time of the last one. Otherwise, you can create a small function like the following one:

+
+
[16]:
+
+

+        [model.START.value, model.FINISH.value], scale="tt", format="mjd"
+    )
+    if (model_time[0].value > observation.tstart.tt.mjd) or (
+        model_time[1].value < observation.tstop.tt.mjd

Now we can see that the ‘PHASE’ column has been added to the table

-
At this point, we also want to add meta data to the table. It is very useful to keep track of what has been done to the file. For instance, if we have multiple pulsars in the same file, we want to be able to know quickly which column correspond to which pulsar. Moreover, experience shows that one often use different ephemeris file for the same pulsar. Therefore, it is very useful to have several phase columns in the same file and to be able to know which column correspond to which ephemeris
-file, parameters, etc.

-
Since there is not yet a “standard” format for such metadata, we propose a template for the essential informations that one wants to save in the header of the event file. First, we look at the present meta info on the table.

4. Save new Event List and writing a modify HDU index table

-
In the following, we show how to write the files in a directory contained in the original datastore directory. This follows the logic of DL3 data store and facilitate the manipulation of the HDU table.

-
If one does not want to save the events files and directly perform the pulsar analysis, this step is not required as well as the step of the meta data handling. However, be aware that for large dataset, the computation of phases can take tens of minutes.

 # This notebook shows how to compute and add the phase information into the events files of pulsar observations. This step is needed to perform the pulsar analysis with Gammapy and should be the first step in the high level analysis. For the pulsar analysis we need two ingredients:
 # 
 # 1. The time of arrivals (TOAs). These times should have very high precision due to the common fast periods of pulsars. Usually these times are already stored in the EventList. For the computation of pulsar timing, times must be corrected in order to be referenced in the Solar System barycenter (SSB) because this system can nearly be regarded as an inertial reference frame with respect to the pulsar.

-# 2. The model of rotation of the pulsar, also known as ephemeris, at the epoch of the observations. These ephemerides are stored in an specific format and saved as .par files and contain informations on the periods, derivatives of the periods, coordinates, glitches, etc.
