[rgb]1,0,0IMAGER is an interferometric imaging package in the GILDAS
software, tailored for usage simplicity and efficiency for
multi-spectral data sets.
The main goals of [rgb]1,0,0IMAGER are
- to offer a proper implementation of imaging in case of
wide relative bandwidth, where the natural angular resolution
changes with frequency.
- to implement a simple and efficient scheme to process Mosaics,
including short spacings from single dish data
- to take advantage of improved capabilities of NOEMA and
ALMA, by offering new tools like self-calibration or wide bandwidth
analysis.
- to simplify user interfaces, by providing sensible defaults.
- to minimize image sizes
- to minimize processing time by using parallel programming as much
as possible and reducing Input/Output to the strict minimum.
[rgb]1,0,0IMAGER was developed and optimized to minimize Input/Output that
are the bottleneck of current computers.
Therefore, [rgb]1,0,0IMAGER works mostly on internal buffers and avoids as
much as possible saving data to intermediate files. File saving is done
ultimately once the data analysis process is complete, which offers an
optimum use of the disk bandwidth.
[rgb]1,0,0IMAGER also includes advanced display and image analysis tools, such as
simple overlaying of different data cubes, etc...
