Status of the CTA medium size telescope prototype
Juergen Baehr
Physics , 2012, DOI: 10.1063/1.4772369
Abstract: We present here the status of the medium size prototype for the Cherenkov Telescope Array. The main reasons to build the prototype are the test of the steel structure, the training of various mounting operations, the test of the drive system and the test of the safety system. The essential difference between the medium size telescope prototype and a fully instrumented are that the camera is not instrumented and only a part of the mounted mirrors are optical mirrors. Insofar no high energy gamma rays can be detected by the prototype telescope. The prototype will be setup in autumn 2012 in Berlin.

Abstract: Pointing calibration is an offline correction applied in order to obtain the true pointing direction of a telescope. The Cherenkov Telescope Array (CTA) aims to have the precision to determine the position of point-like as well as slightly extended sources, with the goal of systematic errors less than 7 arc seconds in space angle. This poster describes the pointing calibration concept being developed for the CTA Medium Size Telescope (MST) prototype at Berlin-Adlershof, showing test results and preliminary measurements. The MST pointing calibration method uses two CCD cameras, mounted on the telescope dish, to determine the true pointing of the telescope. The "Lid CCD" is aligned to the optical axis of the telescope, calibrated with LEDs on the dummy gamma-camera lid; the "Sky CCD" is pre-aligned to the Lid CCD and the transformation between the Sky and Lid CCD camera fields of view is precisely modelled with images from special pointing runs which are also used to determine the pointing model. During source tracking, the CCD cameras record images which are analysed offline using software tools including Astrometry.net to determine the true pointing coordinates.

Further new species of the genus Dolichoctis Schmidt-G bel from New Guinea and surrounding islands (Insecta, Coleoptera, Carabidae, Lebiinae)
Baehr, M.
Animal Biodiversity and Conservation , 2003,
Abstract: Two new species of the carabid genus Dolichoctis Schmidt-G bel from New Guinea and New Ireland are described: D. glabripennis of the striata-group (sensu Baehr, 1999) of the nominate subgenus, from New Guinea, and D. novaeirlandiae of the subgenus Spinidolichoctis Baehr, from the island of New Ireland. In New Guinea, D. glabripennis replaces D. microdera Andrewes of the Greater Sunda Islands and Moluccas that apparently does not occur in New Guinea. D. novaeirlandiae is the first record of a Dolichoctis from this island and it is outstanding due to its very short, only dentate elytra apex.
Tasmanitachoides Erwin glabellus n. sp. from North Queensland, Australia, with a note on Tasmanitachoides lutus (Darlington) (Insecta, Coleoptera, Carabidae, Bembidiinae)
Baehr, M.
Animal Biodiversity and Conservation , 2001,
Abstract: A new species of the genus Tasmanitachoides Erwin from North Queensland is described: T. glabellus n. sp. The species belongs to the T. murrumbidgensis group of species that is characterized by its distinctly impressed clypeus, but it is distinguished from all related species by its glabrous body surface. It is the first Tasmanitachoides from northern Australia to be found in rainforest on high mountains and has thus probably preserved the original habits of the genus that are still characteristic for those species living in southern temperate regions of Australia. Tasmanitachoides lutus (Darlington) so far known from the type locality in southern New South Wales and from the holotype only, is now recorded from eastern Victoria.
New records of the genus Dolichoctis Schmidt-G bel from New Guinea and surrounding islands (Insecta, Coleoptera, Carabidae, Lebiinae)
M. Baehr
Arxius de Miscel-lània Zoològica , 2003,
Abstract: New records of species of the carabid genus Dolichoctis Schmidt-G bel from New Guinea and several surrounding islands are dealt with. Apart from two new species that were described in another recent paper (Baehr, 2003), records of the following species from New Guinea are annotated: D. aculeata Chaudoir, D. biak Baehr, D. dentata Darlington, D. laticollis Baehr, D. striata Schmidt-G bel, D. subquadrata Darlington, D. subrotunda Darlington, and D. suturalis Darlington. D. aculeata Chaudoir is also recorded for the first time from the island of New Britain. Additional material of D. spinipennis Chaudoir corroborates its status as a separate species, being particular for the Moluccas.
