AstroHACK (Holography and Antenna Comissioning Kit) is a python package intended for NRAO telescope support activities, such as holography and antenna position corrections.

Currently AstroHACK supports:

• Astronomical holographies from the VLA.
• Astronomical holographies from ALMA.
• Antenna position corrections for the VLA.
• Near-field ALMA holographies have basic support, such as the creation of Aperture images, but the correction of near-field effects is not yet supported.

In the near term we are working to support the ngVLA antenna prototype comissioning activities. The prototype antenna is currently (March 2025) under construction at the VLA site.

The holography tasks in AstroHACK port much of the functionality of AIPS holography tasks (UVHOL, HOLOG and PANEL) to a python framework that enables us to take advantage of modern parallelization and code acceleration technologies, such as Dask and Numba. Making the reduction of holography data much faster and streamlined for the user.
