This site contains the information and the SMA Miriad version for accommodating data from the new wideband SWARM correlator (SMA Wideband Astronomical ROACH2 Machine) as well as the Legacy ASIC correlator (4GHz BW) with changes of a new SMA data format. The new code has been installed in the public computer systems at CfA. The new Miriad (Miriad-SWARM) is able to handle SWARM data in full spectral resolution¹. Please send us your report concerning errors and bugs in your reduction of SMA data.
