The first near-infrared IFU spectrograph was the 3D instrument , constructed by the Max Planck Institut f r Extraterrestrische Physik. ... An effective slit width of 0.1" was chosen in order to probe to spatial scales approaching the 0.07" diffraction-limited image core size expected from the Gemini adaptive optics system at 2.2 microns while maintaining an acceptable field-of-view. ... The field mirror array then feeds the spectrograph collimator mirror (seen at left in the above figure). ...

... Up: No Title Previous: Mean power spectrum . ... Clearly, this does not imply that the integrands should be equal point-by-point; in fact, there is an infinity of integrands that would meet the integral criterion, each for a different functional basis. It is a matter of interpretation to associate the integrands with an energy density. ... It takes some time and thought to get comfortable with the idea that the Fourier power spectrum is not the absolute answer to spectral energy distribution. ...

... This approach is uniform for all values of the system parameters and applicable to most limb-darkening laws used in astrophysics. In the cases of the linear and quadratic limb-darkening laws, we obtained analytical expressions for the light curve and its derivatives in terms of elementary functions, elliptic integrals and a piecewise-defined function of one variable. ... Besides, they do not allow sufficiently accurate calculations of the light curves for some limb-darkening laws. ...

... The IDL users can call these codes by the CALL_EXTERNAL function with the following syntax: res=CALL_EXTERNAL(libname, 'GET_MW', ParmIn, s, /F_VALUE) Here libname is the name of the appropriate dynamic link library or shared ob ject. ... Then, ParmIn is the 29-element single-precision floating-point array that contains the input parameters for the gyrosynchrotron code, and s is the two-dimensional single-precision floatingpoint array that contains the results of the computation. ...
