... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

... 7.1 Introduction to media types . ... 7.3 Recognized media types . 7.3.1 Media groups One of the most important features of style sheets is that they specify how a document is to be presented on different media: on the screen, on paper, with a speech synthesizer, with a braille device, etc. Certain CSS properties are only designed for certain media (e.g., the 'cue-before' property for aural user agents). ... For example, the 'font-size' property is useful both for screen and print media. ...

... There are several classifications of the exact methods. ... A more physical classification is that of Th.Wriedt (1998) where he devides the methods in 3 groups: Mie theory expansions (SVM), surface-based (PMM, EBCM, GMT, MoM) and volume-based (FDTDM, TLMM, FEM and various volume IEMs - CDM, DDA, etc.) methods. Features of the methods . Among the methods only SVM and EBCM are capable to provide very accurate results (5 and more correct decimals) (Mishchenko et al., 2000). ... 1998) Part. ...

... Lets you work with numeric values. The Number object is an object wrapper for primitive numeric values. ... JavaScript 1.3: added toSource method . ... value . ... JavaScript 1.2: Number(x) now produces NaN rather than an error if x is a string that does not contain a well-formed numeric literal. ... The following example uses the Number object's properties to assign values to several numeric variables: biggestNum = Number.MAX_VALUE . ... ECMA-262 JavaScript prints the value Number.NaN as NaN . ...

... Unsafe act - a behavioral departure from an accepted, normal, or correct procedure or practice which, in the past, has produced injury or property damage or which has potential for doing so in the future; an unnecessary exposure to a hazard; conduct reducing the degree or safety normally present in an activity. ... Any hazardous unsafe condition, or act that presents a situation of imminent danger to life and/or property requires urgent action. ...

... The sky distribution of the BCGs from the HSS sample is shown in Fig. 6 together with BCGs from the SBS and Case surveys (Izotov et al. [ 1993b ]; Pustilnik et al. ... First, we compare the apparent magnitude distributions of the three samples. ... The similar behaviour of the faint end of the apparent magnitude distributions infers that the Northern BCG sample may have a similar completeness down to this limiting magnitude. ...

The possibility to have Visitor Instruments at the VLTI has been granted to permit innovative observations by teams using stand-alone instruments, free from a substantial fraction of the requirements for fully automated VLTI general use instruments. In addition, the Visitor Instruments could provide a powerful scientific/technical test bench for new instrumental concepts, eventually to be incorporated later in VLTI facility instruments. ... a thorough technical description of the instrument, . ...
