The processing of mosaics for NOEMA is essentially similar to that of single fields. There are only two small changes
A mosaicing session would thus just be like a single-field imaging:
1 read uv gag_demo:demo-mosaic 2 uv_map 3 hogbom /flux 0 10 4 fit /jvm 5 uv_restore 6 show sky 7 write * demoComments:
However, mosaics can be huge and require more memory than available (see Section )
To overcome this issue, [rgb]1,0,0IMAGER provides
the script @ image-mosaic that splits the magentaUV_MAP step into slices that fit into memory.
The user can then read the resulting images and deconvolve them, eventually by blocks of channels
if needed (in particular when a magentauv_restore step is desired) using a similar logic.
