| NIKA2 maps of NGC891 at 1mm (Upper) and at 2mm (Lower), after correction for the position angle of 22.5deg. The maps cover 12'x2' and show half-power beamwidths of 12" and 18". Contours show 10% and 50% of the peak flux densities. (CK 17-Jan-2016) | NIKA2 maps of NGC891 at 1mm (Upper) and at 2mm (Lower), after correction for the position angle of 22.5deg.

NGC891
An offline data reduction was made using the 16 scans performed during good weather. The nk pipeline Rev 9881 was used with a single point source as a mask and a single common mode removal. Both 1mm arrays are used and coadded in a single map. Here are the data : say V1
The data will soon be reprocessed by masking the whole edge-on galaxy. Here they are : say V2
