Notes. The objects marked with * have been included for completeness, but they are a part of other observing programs. All the distances are taken from Gaia Collaboration (2018) apart, from the one of HD 98800B, which is from van Leeuwen (2007). References on the peculiarities of each disk are found in the main text.
