This data was observed at the IRAM Plateau de Bure Interferometer 
(now NOEMA). Any publication arising from this data should have the 
appropriate notice that is provided by the IRAM instititue (see

This dataset currently contains the continuum subtracted UV-tables, 
in GILDAS u-v and UVFITS AIPS format for the sources NGC 1333 IRAS 
2A, NGC 1333 IRAS 4A, and NGC 1333 IRAS 4B at 203.4 GHz and 225.9 
GHz observed in the B and C configuration at PdBI (NOEMA). The 
target lines for the publicated project are the H218O line at 203 
GHz and the HDO line at 226 GHz. In addition to this there is also 
the 241 GHz HDO line for NGC 133 IRAS 2A observed in the C 

The data is provided as is, however, with this data it is possible to reproduce the results presented in the paper(s) : "The deuterium fractionation of water on solar-system scales in deeply- embedded low-mass protostars" - Persson et al. (2014) DOI link : "Subarcsecond resolution observations of warm water toward three deeply embedded low-mass protostars" - Persson et al. (2014) DOI link: If any publication is planned that will use this particular dataset, I would greatly appreciate a "heads up", as I am very interested in the re-use and further analysis of this data.
