Dual-band Unified Exploration of Three CMZ Clouds (DUET). The Release of ALMA 1.3 mm and 3 mm Continuum Images and Catalogs

This repository publishes the continuum data sets and catalogs of the DUET project, Dual-band Unified Exploration of Three CMZ Clouds (DUET). Cloud-wide Census of Continuum Sources Showing Low Spectral Indices The ALMA continuum images (in FITS format) are named as, "{Cloud}.{Band}.{Type}.fits" Cloud: the three DUET clouds including The20kmsCloud, SgrC, and SgrB1off (or cloud e in the paper). Band: B3: ALMA band-3 or 3 mm, with the representative frequency of 93.6 GHz. B6: ALMA band-6 or 1.3 mm, with the representative frequency of 226.0 GHz. Type: the image types, including continuum image "cont.image" and primary beam response "cont.image.pb". To reproduce the primary-beam corrected image, one can divide "*cont.image" by "*cont.image.pb". The ALMA continuum catalogs (obtained by getsf, published in latex format) are named as, "{Cloud}.{Cat}_{Beam}_publish.txt" Cloud: the three DUET clouds including The20kmsCloud, SgrC, and SgrB1off (or cloud e in the paper). Cat: the types of catalogs. See more details of each catalog and their comparison in Sect. 3.2 of the paper. mbcat01: 1.3 mm mono-band catalog. mbcat02: 3 mm mono-band catalog. dbcat: dual-band catalog. Beam: the beam type when performing getsf algorithm; commonbeam: dual-band images have a common beam; originalbeam: dual-band images keep their original beams, and 1.3 mm beam is generally smaller than 3 mm beam. Note: you can read the catalogs by Python "astropy.table.Table" Class in the built-in LaTex format, For example, from astropy.table import Table Table.read("SgrC.dbcat_commonbeam_publish.txt", format='latex') We appreciate your citation of our data release paper [the link to the ADS library].
