... ATM written by Juan Pardo is a library of routines for modelling the transmission of radiation at cm/mm/sub-mm wavelengths through the Earth'satmosphere, which is being extensively used by the ALMA calibration software. ...
... With a maximum baseline of 340 meters (~6 times as wide as COAST), the MROI can produce image with the resolution of a single telescope of the same scale while being immune to the negative effects of the Earth'satmosphere to the quality of the image. ...
... 1 INTRODUCTION The Atacama Large (sub-)Millimetre Array (ALMA) will calibrate and correct the effects of the Earth'satmosphere on the phase of the observed radiation by a combination of two techniques: (i) Frequent (every 20200 s, depending on the ...

... Method The on-axis gain of a radio telescope is the constant of proportionality (assuming a completely transparent Earth'satmosphere) between the flux density of a point source, S , and the measured antenna temperature, T A , when the point source is on ...
