Accessing SMA Data
The RTDC machines have a local copy of all raw SMA science data (2004-present), along with the past couple of year worth of flux and baseline data. If you have an account with the RTDC you can log in to any RTDC machine and access SMA data from the locations listed in the table below.
If you are member of R&G and would like an account, email Holly Thomas and supply your CF username.
To access historical non-science data please visit the SMA machines in Hilo.
• ALL data is subject to the 15 month proprietary period. If you are not a member of the project, please limit your access to non-proprietary data only.
If you do not know what file to access, you should visit the SMA Data Archive and use the available filters (source name, project code, tuning etc).
All raw SMA data (science, flux, baseline) is available to external users through the SMA Data Archive. Proprietary data is listed but not available to download, except by the PI and authorized users who should go through the Proprietary Archive.
Online Data Archives
SMA Data Archive The primary science archive. Contains all raw data, including flux and baseline, along with calibrated and imaged science.
Science data taken with the ASIC correlator have typical raw file sizes of ~10GB. The increase in sizes from 2015 shows the introduction of SWARM chunk by chunk. SWARM reached it's full 4 chunk (8GHz) bandwidth in the second half of 2016. Since then file sizes have been regularly exceeding 100GB. The largest files are those with short scan times such as large maps covering a large number of pointings. Be aware of the size of your data and consider rebinning them using SMARechunker.
