Multi-degree Data Cubes
The 100 square degrees of the HOPS region has been broken into eleven strips. Here you can download data from each of these strips. For each strip, there are six basic data products:
1. Full data cube produced at Step 4 of the data reduction routines. These cubes are appended as "cube.fits".
2. RMS noise 2D map, produced at Step 7 of the data reduction routines. The RMS noise map can be used, together with the full data cube to examine the noise characteristics of HOPS or to reproduce the signal-to-noise data cube. These 2D maps are appended as "rms.fits"
3. Duchamp final mask cube. Non-zero voxels in this cube denote where real emission was found by Duchamp. The number associated with each voxel corresponds to the clump number found in the data catalogue. These cubes are appended as "mask.fits".
4. 2D Duchamp final mask map. These maps are masked so that each pixel containing a non-zero number exhibits emission in its spectrum. These maps are appended as "mask2D.fits".
5. Integrated intensity (moment-0) maps created using only voxels containing detected emission. These maps are appended as "mom0.fits".
6. Peak signal-to noise map. These maps have been created from a smoothed version (beam FWHM=150 arcsec, hanning-smooth=5 channels) of the cube in which each plane has been divided by the RMS noise map (above) and the value of the brightest channel in each spectrum plotted. Such maps are very useful in determining if there is any emission at a particular position. These maps are appended as "peakSN.fits".
Note: All FITS files have been placed onto the Tmb temperature scale by dividing by the Mopra main-beam efficiency at the relevant frequency. The efficiency used in each case is recorded in the non-standard FITS header-card "ETAMB".
