Dataset: The dynamic centres of infrared-dark clouds and the formation of cores

The tar archive for each of the seven IRDCs covered by NOEMA observations contains twelve files which are: <IRDC>-USB-lores-filt-cont.fits.gz – Upper side band (2.8 mm) continuum image<IRDC>-LSB-lores-filt-cont.fits.gz – Lower side band (3.2 mm) continuum image<IRDC>-SPW03-HCOp-uvb-merged.fits.gz – HCO+ (1-0) data cube<IRDC>-SPW05-HNC-uvb-merged.fits.gz – HNC (1-0) data cube<IRDC>-SPW07-N2Hp-uvb-merged.fits.gz – N2H+ (1-0) data cube<IRDC>-SPW17-C18O-uvb-merged.fits.gz – C18O (1-0) data cube in addition to an accompanying version suffixed with -prim.fits.gz which is the primary beam-corrected version, trimmed to the area where the primary beam response is > 0.5.
