Next: Reading and Writing Continuum Up: UV Data Sets Previous: Open, Close and Rewind . The routines uvread and uvwrite are routines used to read and write the correlation data (and the associated flagging information). Here preamble is an array of four double precision elements, data is an array of n complex elements, whereas flags is an array of n logical values. ... Using uvflgwr when reading a visibility file, is the method used to develop flagging tasks. ...

Fasti is an innovative design for infrared detector control. The present-day commercial electronics for reading bi-dimensional near-infrared array detectors often lack useful feature as quick sub-array fast acquisition, or is based on old components, or cannot cope with newer devices, as the 2048x2048, multi--output Rockwell Hawaii-2. ... Named Fasti , it is meant to be a "light" electronic system, which is modular, flexible, extendible, and avoids obsolescence as much as possible. ...

TEST RESULTS WITH 2KX2K MCT ARRAYS Finger, G, Dorn, R.J., Mehrgan, H., Meyer, M., Moorwood A.F.M. and Stegmeier, J. European Southern Observatory Abstract: The performance of both an LPE 2Kx2K engineering grade and a science grade array have been evaluated. Both arrays have a cut-off wavelength of c=2.6 µm. At an operating temperature of 60 K, the dark current of the science grade array is 0.004 e/s. The peak quantum efficiency of the science grade array is 84.4%. ...

Python is a powerful, object-oriented scripting language that is easy to extend, free, and available for most computer platforms. Python, together with its Numerical module, and with the pFitsio module that is being developed by one of the authors, provides an attractive alternative to other languages such as Perl, IDL, and the IRAF CL, which are already widely used by the community. ...
