The GBT-EDGE CO(1-0) Survey Dataset

Official data release for the GBT-EDGE CO(1-0) Survey across nearby galaxies, associated with the paper: "The EDGE-CALIFA Survey: Star Formation Efficiency and Galaxy Quenching across 62 Main Sequence, Green Valley, and Red Galaxies" (Teng et al. 2026, The Astrophysical Journal). Please cite the paper if you use any of these data. The information included in this dataset can be found below or in the README file. ## Content of the data release These folders contain reduced CO(1-0) data of all 62 galaxies in the GBT EDGE survey (Y.-H. Teng et al. 2026, ApJ). - The 'cubes' folder contains 62 data cubes (one per galaxy). - The 'maps' folder includes 4 sub-directories: 1. tpeak-rms * Peak temperature maps: *GALNAME_12CO_Tpeak_seXXX.fits* * Error (rms per channel) maps: *GALNAME_12CO_rmsmap_seXXX.fits* 2. moment-0 * Integrated intensity maps: *GALNAME_12CO_mom0_Havexpand_seXXX.fits* * Associated uncertainty maps: *GALNAME_12CO_emom0_Havexpand_seXXX.fits* * For Mrk1418, file names are slightly different as a 'block' masking is used -> *Mrk1418_12CO_mom0_block_seXXX.fits* 3. moment-1 * Intensity-weighted velocity maps: *GALNAME_12CO_mom1_Havexpand_seXXX.fits* * For Mrk1418, use *Mrk1418_12CO_mom1_block_seXXX.fits* 4. moment-2 * Velocity dispersion maps: *GALNAME_12CO_vdisp_Havexpand_seXXX.fits* * For Mrk1418, use *Mrk1418_12CO_vdisp_block_seXXX.fits*
