Brief Description:
We release a collection of Metadata to accompany EHT Observations taken in April 2017. This includes a priori estimates of station sensitivity for all EHT 2017 scans in ANTAB format, as well as control codes for configuring and reducing EHT data in the CASA and HOPS radio interferometry software environments. Metadata in this package can be used as auxiliary information to process original EHT correlator output in FITS-IDI or Mark4 format. Data that has already been reduced and calibrated are provided in accompanying EHT publications, see for example EHTC 2019c (Paper III).
Further information about EHTC released data sets can be found at the URL,
