EHTIM

A (very!) thin wrapper for ehtim (eht-imaging) Python package, see https://github.com/achael/eht-imaging

Installation

You have to install ehtim Python package manually. Maybe it is easiest to first install miniconda2 and set PyCall to use it, e.g.

ENV["PYTHON"] = "/home/kjwiik/miniconda2/bin/python"
] add PyCall Pkg
using Pkg
Pkg.build("PyCall")

Then install ehtim and pynfft in miniconda2 environment:

conda activate
conda install -c conda-forge pynfft
pip install ehtim

Usage

using EHTIM
eht = EHTIM.new()
testdata = eht.obsdata.load_uvfits("test.uvf", polrep="circ")
tstokes = testdata.copy().switch_polrep("stokes")
tstokes.plot_bl("AA","AP","amp",color="blue",legend=true,label="AA-AP")

data = tstokes.unpack_bl("AA", "AP", ["amp","phase","sigma"])|>structarray

structarray()

structarray() converts a structured numarray from unpack and unpack_bl to Julia StructArray and handles now all types that Julia supports in the obsdata object. If mode is set (Array of objects is returned), numarray returns a Julia array of StructArrays. Numeric arrays are converted without a copy, Unicode arrays are copied.

bldict()

bldict() converts an array of StructArrays from structarray() to a Dict of baselines if the underlying objects contain telescope identification information (t1 and t2).
