Stochastic calibration of radio interferometers

We propose a 'stochastic' calibration strategy where we only read in a mini-batch of data for obtaining calibration solutions, as opposed to reading the full batch of data being calibrated.  ...  Nonetheless, we obtain solutions that are valid for the full batch of data. Normally, data need to be averaged before calibration is performed to accommodate the data in size-limited compute memory.  ...  In section 2, we introduce the data model we use in radio interferometry. In section 3, we present distributed stochastic calibration of multi-frequency radio interferometric data.  ...

Multiple gain and multiplexing stages as well as programmable analog and digital hardware blocks allow for the acquisition, processing, and communication of single-ended and differential signals.  ...  Fiber optic sensors and their application in DMIs are briefly discussed, as well as the use of the hardware platform with specific musical interfaces.  ...  If enabled, data can be printed without polling to the USB port at a rate and in an order selectable at run-time. Otherwise data can be polled over I2C or USB.  ...
