pvhub

Function to predict peculiar velocities given RA (right ascension), Dec (declination), and z (redshift). All maps are in redshift-space. All maps are limited to z < 0.067 with a flag in the function for extrapolation option. Conversion from real-space to redshift space as well as the extrapolation option are explained by Carr et al. (2021).

Maps:

The number of each map is the corresponding flag in pvhub.py

default

0. 2MPP-SDSS (Said et al. 2020; Peterson et al. 2021; Carr et al. 2021)

Other available maps

1. 2MPP-SDSS_6dF (Said et al. 2020)
2. 2MRS (Lilow & Nusser 2021)
3. 2MPP (Carrick et al. 2015)

Cloning

The PV maps are large files, so to properly clone this repository you must download them individually from this webpage or use Git Large File Storage.

Mac

brew install git-lfs
git lfs install
git lfs clone https://github.com/KSaid-1/pvhub.git

Linux

sudo apt install git-lfs
git lfs install
git lfs clone https://github.com/KSaid-1/pvhub.git

Windows

If you have Git Bash, install Git LFS using the installer, then continue as normal in Git Bash:
