... LO frequencies were 1/2, 1/3 and 1/8 of signal frequency 75 GHz. ... But single junction SIS mixer has 30 dB input signal power range only [ll and it may decrease at high frequencies more than 200 GHz due to Josephson and 1 "switching" noise rise [2 e Our experiments show that subhurmonically pumped SIS mixer may have improved saturation power and reduced noise at high frequencies in some operation modes. ... 269 Fig.2 Quantum for LO and signal frequencies SIS operating mode. ...

... NICMOS data are represented by five arrays for each readout. ... Samples array. ... Each downlinked readout is always represented by these five arrays ( Figure 13.4 ). Multiple readouts in the same dataset (e.g., MULTIACCUM data) are represented by repeated sets of these five arrays ( Figure 13.5 ). ... For data where multiple samples of the array were obtained during the integration, the samples array denotes the number of samples for each pixel in the corresponding science image. ...

M100 is a challenging target. It has a diameter of 5.5 arcminutes and a total integrated magnitude of around 9.5. It is an excellent example of disk galaxy which has strong spiral structure. The Hubble pictures refer to only the inner 2.5x2.5 arcminutes of the galaxy, which corresponds to the brighter regions in the ground based blue CCD image.

... In this section, we develop a physical model of the secondary as a disk that is centrifugally supported in the radial direction and hydrostatically supported in the vertical direction. We assume that the disk is vertically isothermal and well mixed. ... where is the mean molecular mass of the gas, is the orbital period at the outer edge of the disk in years, and all of the mass of the secondary has been assumed to be concentrated near its center, so the Keplerian approximation is valid. ...

... We present a new code for evolving three-dimensional self-gravitating collisionless systems with a large number of particles . FLY (Fast Level-based N-bodY code) is a fully parallel code based on a tree algorithm. ...
