Tools

The tools module provides wrappers around other common data processing tools.

DP3

DP3 (DPPP - Default Pre-Processing Pipeline) is used for various operations on Measurement Sets including: averaging, flagging, calibration, and more.

from taitale import taitale_env
from taitale.tools import dp3

env = taitale_env(runtime="native")

# Using direct arguments
dp3(
    env=env,
    args={
        "msin": "input.ms",
        "steps": "[average]",
        "average.type": "averager",
        "average.timestep": "8",
        "msout": "output.ms",
        "msout.datacolumn": "DATA",
    },
)

# Using a parset file
dp3(
    env=env,
    parset="dp3.parset",
)

For more information on DP3, see the DP3 documentation.

LoSoTo

LoSoTo (LOFAR Solution Tool) is a tool for processing and manipulating solution tables generated during calibration.

from taitale import taitale_env
from taitale.tools import losoto

env = taitale_env(runtime="native")

# Plot amplitude solutions
losoto(
    env=env,
    h5parm="solutions.h5",  # H5Parm file containing solutions
    args={
        "soltab": "sol000/amplitude000",
        "operation": "PLOT",
        "axisInTable": "time",
        "axisInCol": "ant",
        "plotFlag": "True",
        "prefix": "amp_",
    },
)

# Smooth solutions using a parset file
losoto(
    env=env,
    h5parm="solutions.h5",
    parset="losoto_smooth.parset",
)

WSClean

WSClean (w-Stacking Clean) is an advanced radio interferometric imager.

from taitale import taitale_env
from taitale.tools import wsclean

env = taitale_env(runtime="native")

# Basic imaging
wsclean(
    env=env,
    args="-size 1024 1024 -scale 1asec input.ms"
)

# Advanced imaging with multiple parameters
wsclean(
    env=env,
    args=(
        "-size 2048 2048 -scale 0.5asec "
        "-niter 1000000 -auto-threshold 0.3 "
        "-auto-mask 3 -mgain 0.8 input.ms"
    )
)
