Astrometry in Wide-field Surveys
We present a robust and fast algorithm for performing astrometry and source cross-identification on two dimensional point lists, such as between a catalogue and an astronomical image, or between two images. The method is based on minimal assumptions: the lists can be rotated, magnified and inverted with respect to each other in an arbitrary way. The algorithm is tailored to work efficiently on ...
متن کاملUtilizing Repeated Gps Surveys from Field Operations
Topographic data collected using RTK‐DGPS‐equipped farm vehicles during field operations could add additional benefits to the original capital investment in the equipment through the development of high‐accuracy field DEMs. Repeated surveys of elevation data from field operations may improve DEM accuracy over time. However, minimizing the amount of data to be processed and stored is also an imp...
متن کاملWide Field Surveys of Herbig-Haro Objects
We report our new results from wide-field surveys of Herbig-Haro (HH) objects in the nearby star forming regions. The surveys covered approximately 56 deg in Perseus, Taurus, Orion, Monoceros, and other regions. Using refined techniques, we discovered in total 68 HH objects, of which 32 were in Perseus, 4 in Taurus, 13 in Orion, 18 in Monoceros, and 1 in S287 regions. The newly discovered HH ob...
متن کاملDeep Field Surveys - a Radio View
I present an introductory review text, focusing on recent deep field studies using radio telescopes, including high-resolution, widefield VLBI observations. The nature of the faint radio source population is discussed, taking into account complimentary data and results that are now available via the sub-mm, IR, optical and X-ray wavebands. New developments regarding the increased sensitivity of...
متن کاملMobile Support for Team-Based Field Surveys
This paper describes a study of the use of multimedia networked location-aware mobile computers to support team-based survey-oriented fieldwork. Existing systems do not provide fully integrated support for collaborative data capture and review, or access to distributed real time information on survey progress and status, all of which are crucial for the conduct and management of surveys often c...
