NE2001 Installation Instructions¶
When you install FRUITBAT it automatically installs the YMW16 galactic
electron density model
pyywm16 from PyPi. However, if you have the python
port of the NE2001 model by Ben Baror and JXP you can use it with FRUITBAT
to estimate the galactic contribution to dispersion measure.
The python port that is compatible with FRUITBAT is found at: https://github.com/FRBs/ne2001.
You will need to download and install the NE2001 model to use it.
Installing the NE2001 model¶
>>> git clone https://github.com/FRBs/ne2001 >>> cd ne2001 >>> pip install .
Using the NE2001 model¶
After installing the NE2001 model, it behaves exactly the same as the YNW16 model.
To specify that you want to use the NE2001 model pass “ne2001” as a keyword in
>>> import fruitbat >>> FRB190523 = fruitbat.Frb(760.8, gl="117.03", gb="44") >>> dm_galaxy_ymw16 = FRB190523.calc_dm_galaxy(model="ymw16") >>> dm_galaxy_ne2001 = FRB190523.calc_dm_galaxy(model="ne2001") >>> print(dm_galaxy_ymw16, dm_galaxy_ne2001) 29.88017464 pc / cm3 36.87013932 pc / cm3
