rtpipe 1.46

Python scripts for fast transient searches with radio interferometer data

rtpipe
==

rtpipe (as in 'real-time pipeline') is a Python package for searching visibility data from radio interferometer data for fast (subsecond) transients. In contrast to traditional time-domain techniques used on large single-dish telescopes or "phased" interferometers, fast-sampled visibilities can precisely localize sources anywhere in the entire field of view. This package supersedes [tpipe](http://github.com/caseyjlaw/tpipe) and uses a paradigm that defines how to break long (large) data into smaller, independent pieces with a single treatment (flagging, image gridding, calibration, etc.).

Requirements
---

* Python 2.7
* Standard scientific Python stuff: numpy, scipy, matplotlib, multiprocessing, bokeh
* [pwkit](http://github.com/pkgw/pwkit) (for access to CASA libraries)
* Cython (tested with 0.19.1)
* [sdmpy](http://github.com/caseyjlaw/sdmpy) (for reading SDM format data)
* [pyFFTW](https://pypi.python.org/pypi/pyFFTW) (accelerated FFTs; tested with 0.92)

Install
---
conda install numpy scipy jupyter bokeh cython matplotlib
conda install -c pkgw pwkit casa-tools casa-python casa-data
pip install rtpipe

pwkit is needed to access CASA libraries and so the anaconda installer is thus required. Alternatively, one can build pwkit and environment variables set like so to see libraries of an existing CASA installation:

setenv CASA_HOME /home/casa/packages/RHEL6/stable/current
setenv PYTHONPATH ${PYTHONPATH}:${CASA_HOME}/lib/python2.7
setenv LD_LIBRARY_PATH ${LD_LIBRARY_PATH}:${CASA_HOME}/lib
setenv CASAPATH "${CASA_HOME} linux local ${HOST}"

The trick here is being sure that the python interpreter is binary-compatible with that used to build CASA.
