At NOEMA, RDI produces IPB (which stands for
Interféromètre du Plateau de Bure) files, one for each track. A
track consists of observations of one scientific subproject and last a
few hours (typically two to ten hours). The IPB file produced at NOEMA
contain sections (-2,-3,-21,-22,-23,-24,-25,-26,-30,-32,-35,-37) and
of course the raw data themselves. Following the online atmospheric
calibration, data are on a temperature scale in
(i.e. the
coupling factor considered in the atmospheric calibration is the
forward efficiency). Contrary to single dish, one does not need to
worry about the temperature scale as after amplitude calibration, the
visibilities are in Jy. These files are stored in the NOEMA archive
and can be accessed from IRAM computers using the getproj
command.
