AVICA: Automated VLBI pipeline in CASA#
AVICA is a Python package for automated calibration of Very Long Baseline Interferometry (VLBI) data in CASA. It provides tools to ingest, manipulate, and calibrate FITS-IDI and Measurement Set files containing raw visibilities.
Quick start#
Install AVICA:
uv tool install avica --python 3.10
The calibration steps use rPICARD and CASA. To install AVICA, CASA and rPICARD together, use the installation script described in Installation.
Create an avica.inp next to your data with at least:
folder_for_fits = /path/to/folder/with/fitsfiles
casadir = "path/to/monolithic-casa/casa-6.x.x-xx-py3.xx.xxx/"
Then run the pipeline and check how it went:
avica pipe run --target <target-name> --fitsfilenames <file1.uvfits,file2.uvfits>
avica pipe result --target <target-name>
