ALMA-IMF N2H+ 12m+ACA+TP cubes

N2H+ (1-0) ALMA-IMF partial data release (April 7 2025) We provide the combined 7m and 12m observations feathered with Total Power for the G351 and G353 ALMA-IMF regions. These data are primary beam corrected (pbcorr). The N2H+ kinematic analysis on some of these regions can be found in Álvarez-Gutiérrez et al. (2024) and Sandoval-Garrido et al. (2025). For each field we provide the full N2H+ emission, containing all hyperfine components, and a separate version, derived from the pbcorr data which only considers the isolated component emission (see Álvarez-Gutiérrez et al. 2024). The full line emission can be found in the files ending with 'pbcorr.fits' and the isolated component emission in files ending with 'isolated_component.fits'. Full line emission cubes containing 'JvM' are the product of applying the JvM correction (Jorsater & van Moorsel 1995) as presented in Cunningham et al. (2023) and included in the ALMA-IMF pipeline. The isolated component cubes from these regions are derived from their JvM corrected pbcorr full line emission cubes. Please note that in the case of multiple velocity components the most red-shifted isolated component might not be well captured by our approach, creating discontinuities on small areas of the maps. This artifact can be caused when multiple velocity components in a single spectrum cover a wide range of velocities of about 8 km/s.This is the velocity offset between the main N2H+ line emission and its isolated component, resulting in line blending between (part or the entirety of) the most red-shifted isolated component and part of the main N2H+ line emission. Those cases escape the criteria we use in our approach to identify the isolated component emission, and it will select a velocity cut that might produce a sharp intensity drop in the spectrum, seen as discontinuities in the data cubes. Another case is that when having multiple velocity components, one of our velocity guesses might land on the peak (or at least high intensity emission) of one of the isolated components, and a guess with lower intensity might be selected, even if does not capture the most red-shifted velocity component.
