Zenith (building)

The Zenith is a culture and exhibition centre, converted from an old railway reparation hall, located in Freimann, Munich, Germany.

The centre hosts concerts, fairs, company presentations and parties. The centre can hold up to six thousand people and has a floor area of 5046 m². The main stage is 24×16 metres in area. Its capacity is approximately 7,000 people

History

The building is of a unique architectural style, and formerly served as a railway construction and reparation hall. It was originally built from 1916 to 1918. The building is protected.

Zenith camera

A zenith camera is an astrogeodetic telescope used today primarily for the local surveys of Earth's gravity field. Zenith cameras are designed as transportable field instruments for the direct observation of the plumb line (astronomical coordinates) and vertical deflections.

Instrument

A zenith camera combines an optical lens (about 10–20 cm aperture) with a digital image sensor (CCD) in order to image stars near the zenith. Electronic levels (tilt sensors) serve as a means to point the lens towards zenith. Zenith cameras are generally mounted on a turnable platform to allow star images to be taken in two camera directions (two-face-measurement). Because zenith cameras are usually designed as non-tracking and non-scanning instruments, exposure times are kept short, at the order of few 0.1 s, yielding rather circular star images. Exposure epochs are mostly recorded by means of the timing-capability of GPS-receivers (time-tagging).

Data processing

Depending on the CCD sensor - lens combination used, few 10s to 100s of stars are captured with a single digital zenith image. The positions of imaged stars are measured by means of digital image processing algorithms, such as image moment analysis or point spread functions to fit the star images. Star catalogues, such as Tycho-2 or UCAC-3 are used as celestial reference to reduce the star images. The zenith point is interpolated into the field of imaged stars, and corrected for the exposure time and (small) tilt of the telescope axis to yield the direction of the plumb line.

Zenith (disambiguation)

The zenith is the point in the sky that appears directly above the observer (opposite: nadir).

Pure (The Lightning Seeds album)

Pure is a compilation album by pop band The Lightning Seeds, released in 1996 and reaching #27 in the UK Albums Chart.

The first of what would turn out to be five compilations Ian Broudie released from 1996 to 2006, Pure, The Lightning Seeds' first release by Virgin, is almost a reissue rather than a compilation, since it consists of all but three of the songs released by Epic on the first two albums, Cloudcuckooland from 1990 and Sense from 1992; the only songs missing are one song from the first album ("Control the Flame") and two from Sense: ("Where Flowers Fade" and "Marooned").

All songs written and composed by Ian Broudie; except where indicated.

Pure (Hayley Westenra album)

Pure is the first internationally published album by Christchurch, New Zealand soprano Hayley Westenra. Her previous albums were released only in New Zealand and nearby Australia. This album also received professional consultation from the legendary Sir George Martin who helped to create its "unique appeal". In 2004, it was the highest selling New Zealand Album and so it privileged Hayley with an award from the New Zealand Music Awards of 2004. It was published by the Decca Music Group label in 2003. It was distributed in the United States by Universal Classics in 2004. During its first week of sales it sold 19,068 copies. As of 2007, Pure is the best selling classical album for the 21st century in the UK.

Pure gives a new freshness to well known classical repertoire, as well as exploring the world of pop and traditional Maori choral singing, including renditions of "Who Painted the Moon Black?", "Hine e Hine" (a song of the Māori, the natives of New Zealand), "In Trutina", from Orff's Carmina Burana, "Wuthering Heights" (a cover of the Kate Bush hit), and the perennial spiritual classic "Amazing Grace". Sir George Martin co-wrote the track "Beat of Your Heart" just for the album. Also on the album is "Pokarekare Ana", a New Zealand love song which has enduring popularity, and has become Hayley's signature song.
