We are working on the system of duplication and distribution for the Miriad-SWARM software for SMA data reduction and imaging to support the next generation of the SMA backend equiped with a new SWARM correlator. We are in the transition phase from the legacy ASIC correlator to the SWARM correlator. Before the new software distribution system to be established and stabilized, we recommend users who are not able to access CfA computer systems to follow the guideline below for the reduction of SMA SWARM data or ASIC data in new format using the SMA Miriad software that has been distributed globally:

IDENTIFY SMA DATA SET -

• e.g. 150519_09:50:17 (for ASIC+SWARM hybrid configuration)
• e.g. 170717_09:31:42 (for Dual RX SWARM configuration)

PRE-PROCESSING SCRIPT -

For Dual RX SWARM data -
• swarmDRXload.csh & Download
• Handling Frequency Configurations produced from DRX modes
Example scripts -
• Two Frequency Configurations from RX 230 and 240
• Two Frequency Configurations from RX 340 and 240
• SIngle Frequency Configuration from any pair of RXs

For ASIC+SWARM hybrid data -
• swarmload.csh or asicload.csh
• A SMA Technical Memo for the Miriad task: SWARMSPLT
  to pre-process new data produced from the hybrid SWARM & ASIC correlator

REQUEST FOR HELP -

Send a request to RTDC or smamiriad@cfa.harvard.edu
with the file-name of your data (e.g. 150519_09:50:17) for pre-processing the data with above script; and they will send back users a link for downloading the Miriad-formatted data files output from this pre-processing, e.g. for swarm + asic data:
LSB:

• 150519_rx0.lsb.asic
• 150519_rx0.lsb.sw1
• 150519_rx0.lsb.sw2
USB:

• 150519_rx0.usb.asic
• 150519_rx0.usb.sw1
• 150519_rx0.usb.sw2

which are fully compatible with the latest version of the well tested and stable SMA Miriad software for global distribution - SMA-Miriad 1.5.1
The output files from the pre-processing are packed in two tar-balls for users' downloading, e.g.:


• 150519_rx0.lsb.tar
• 150519_rx0.usb.tar

MIRIAD DOWNLOAD -

• DOWNLOAD - SMA-Miriad 1.5.1 RH 6 or CentOS 6
• BINARY INSTALLATION - Redhat & CentOS
• README - Release History
• ORTHER OS's -
• For MacOS X users
VMware Fusion is recommended.
• For Ubuntu users
Miriad distributed by CARMA/BIMA via UMD is recommended.

CALIBRATION/IMAGING SCRIPTS -

Then, experienced users can follow the example scripts (with some minor editing) for further calibrations and imaging in Miriad:
• SMA-Miriad 1.5.1: Data reduction scripts

For fresh users , a set of C-shell scripts are provided based on the reduction of a recent CO (2-1) observation for an external galaxy with the new hybrid ASIC and SWARM correlator:
• SMA-Miriad 1.5.1: editing & calibration for ASIC data -
• swarmcali_a.csh (Download)
• SMA-Miriad 1.5.1: Imaging CO(2-1) & H30a lines from an external galaxy -
• imagingln_CO21.csh (Download)
• imagingln_H30a_mosaic.csh (Download)
