The Spitzer Legacy Program "From Molecular Cores to Planet Forming Disks" ("Core to Disks" or "c2d") is a motivation for acquiring complementary data on dense cores of star forming regions.
The maps were acquired using the MAMBO-1 (37 receiver) and MAMBO-2 (117 receivers) bolometer arrays operated at the IRAM 30m-telescope in Granada, Spain. These data were obtained by scanning the telescope across the sky, with the telescope's secondary mirror chopping parallel to the scan pattern. They were reduced using the iterative data reduction scheme described in the associated publication. This allowed to image the faint (few mJy per 11 arcsec beam) extended (up to 5 arcmin) emission from the cores. The data presented here have been filtered for sky-noise (as indicated by the "snf" file name extension) and were smoothed to a resolution of 20 arcsec (as indicated by the "gsm20" extension). Higher resolution data can be provided by the author on request. To keep the data comparable between maps of different resolution, the intensities are still calibrated in mJy per 11 arcsec beam though. Also included in this release are the associated noise maps (indicated by the "noise" extension). These predict, based on the achieved integration time, the root mean square noise level across the mapped areas. The absolute calibration uncertainty is probably of order 20%. The maps cover several fields, which themselves can contain several target dense cores.
