# Summary
There are several standard formats for astronomical interferometric data, but
converting between them in a stable and repeatable way has historically been
very challenging. This is partly because of subtle assumptions in the
implementations of the formats and the complexity of the mathematical
relationships between the different formats (e.g. drift mode vs phased data)
and partly because data analysis for individual telescopes
typically used just one of the standards along with the associated analysis
code. New low frequency instruments (e.g. MWA (http://www.mwatelescope.org/),
PAPER (http://eor.berkeley.edu/), HERA (http://reionization.org/)),
have required custom analysis and simulation software that rely on a range of
different file formats. pyuvdata was designed to facilitate interoperability
between these instruments and codes by providing high quality, well documented
conversion routines as well as an interface to interact with interferometric
data and simulations directly in python.
pyuvdata currently supports reading and writing uvfits [@uvfits] and
miriad [@miriad] files and reading FHD [@fhd] visibility save files.
