tart 1.4.5

Transient Array Radio Telescope Imaging and Operation Library

TART: Radio-telescope operating software

This module is used for the operation and imaging from the open-source Transient Array Radio Telescope (TART).

Installation

Default installation (includes all features):

pip install tart

For minimal installation (without scipy simulation features):

pip install tart[minimal]

For installation with plotting support:

pip install tart[plotting]

For complete installation (all optional features including networking and performance enhancements):

pip install tart[all]

Note: The [all] option includes jsonrpclib, matplotlib, pyfftw, requests, and scipy for complete functionality. Some simulation features require scipy and plotting features require matplotlib. These are optional dependencies that will provide helpful error messages if missing. The spectrum analysis feature now works in minimal installations using numpy.fft instead of scipy.fft.

Development work

If you are developing this package, this should be installed using

	make develop

in which case changes to the source-code will be immediately available to projects using it.
