Processing SMA Data
1.2 m Telescopes
The Radio Telescope Data Center (RTDC) archives, and makes available data from the Submillimeter Array (SMA), the CfA Millimeter-wave Telescope, the Antarctic Submillimeter Telescope and Remote Observatory (AST/RO). We also provide hardware, software tools, and necessary support for the analysis of radio interferometric data from the SMA, JVLA, VLBA, and ALMA.
RTDC machines give users access to all raw SMA science data since 2002, and flux and baseline data going back two years. We also maintain a public data archive containing all SMA data from which visitors can download non-proprietary raw datasets. A subset of calibrated and imaged science data is also available.
The CfA Millimeter-wave telescope archive includes the CO (1-0) spectra from the whole-Galaxy survey presented in Dame, Hartmann & Thaddeus (2001), v-l-b FITS cubes for each survey listed in Table 1 of that paper, plus larger composite cubes and integrated maps.
