SMA/VLA data toward five CMZ clouds (20 km/s, 50 km/s, G0.253+0.016, Sgr B1-off, Sgr C) and Sgr D. Details of these images can be found in the published paper Lu et al. 2019, Astrophysical Journal, vol. 872, article id. 171 (https://ui.adsabs.harvard.edu/abs/2019ApJ...872..171L/abstract). The files are named as follows: [Target]_[Telescope]_[Lines(or continnuum)]_[Imagecontent].fits The target is one of 20kms, 50kms, G0253, SgrB1off, SgrC, and SgrD. The telescope is either SMA (for the Submillimeter Array) or the VLA (for the Karl G. Jansky Very Large Array). The lines/continuum is continuum, H2Omaser (for VLA data), or CH3OH/SiO (for SMA data). The image content is either IM (images without primary beam correction) or PB (primary beams). To apply the primary beam correction and get the flux-corrected images, divide IM by PB pixel-by-pixel (for related CASA tasks, see https://casa.nrao.edu/docs/taskref/impbcor-task.html) For example, 20kms_SMA_CH3OH_IM.fits -- the target is the 20 km/s cloud; -- the telescope is the Submillimeter Array; -- the observed line is the CH3OH 4(2,2)-3(1,2) transition; -- the file is the image without primary beam correction.
