IVOA NEWSLETTER
US VAO Data Discovery Portal 
Find datasets from thousands of astronomical collections known to the VO and over wide areas of the sky. This includes important collections from archives around the world. Feedback on your experience with the tool is appreciated -- please send your comments, suggestions, and questions to the VAO Help Desk.
 
US VAO Cross-Comparison Tool 
Perform fast positional cross-matches between an input table of up to 1 million sources and common astronomical source catalogs, such as 2MASS, SDSS DR7 and USNO-B. Feedback on your experience with the tool is appreciated -- please send your comments, suggestions, and questions to the VAO Help Desk.
 
VOPlot v1.8 Beta 
VOPlot v1.8Beta includes many enhancements and bug fixes. To name a few v1.8Beta supports multi-grid plots for 2D Scatter-Plot which allows the user to have multiple plots having grid size from 1x1 to 3x3 in a single window. Paginated view is added to see data in tabular format which allows user to navigate systematically. Provision to label Lat/Long lines is also added. Users can now plot a cumulative histogram for all histogram types. VOPlot 1.8Beta shows the metadata of a FITS file instantaneously while the actual loading happens in background. VOPlot v1.8Beta also provides better handling of "faulty data" while parsing an ASCII file.
 


   Software for Automatic Detection of Asteroids and Comets CoLiTec 

CoLiTec (CLT) is the software package dedicated for the automatic discovery of any moving objects such as asteroids, comets, space debris and so on. The first project carried on by the group yielded the first (on the territory of CIS) automatic discovery of an asteroid (May 2010), done by observers from Andrushivka astronomical observatory. 35 asteroids have been discovered despite the bad astronomic weather within this observatory (April 12, 2011) using the present software. The software is under continual refinement. For the end of 2010 the present software was used by 3 CIS observatories.

Since November 27, 2010 oLiTec (LT) has been successfully used by Russian remotely ISON-NM observatory (Mayhill, New Mexico, USA) within its project dedicated to the observation and cataloging of space debris ISON (International Scientific Optical Network), managed by Igor Molotov. More than 300 asteroids have been discovered in this observatory using the present software (dedication to the 50th anniversary of the first humans flight in space April 12, 2011)

December 10, 2010 Leonid Elenin (Russian astronomer, scientific associate of Keldysh Institute of applied mathematics, ISON-NM leading asteroids observer) discovered the comet C/2010 X1 (Elenin) using oLiTec. That was the first discovery made by a Russian astronomer for the last 20 years. The Comet Elenin is moving in ecliptic plane and in October 2011 will be so close to the Earth that it will be for some time visible to the naked eye. As a result the Comet Elenin was widely discussed in the international media.

By the end of 2011 the present astrosoft will be able to discover asteroids approaching the Earth, new stars and supernovas; automatically define tracks of meteors.

   Software functions 

The present software is based on the original computational method of light collection that permits to accumulate objects signals along the tracks with undefined motion parameters using multivalued coordinates transform. Hierarchical implementation of transform stabilizes computational cost of the method.

Software input data:

  • preliminary processed frames of astronomic observation in FITS format including readout noises (bias frames), dark current (dark frames) and uneven pixels sensitivity of CCD-matrix (flat field frames);
  • electronic stellar catalogs USNO A2.0, USNO B1.0, UCAC 3.0, XPM;
  • settings for telescope CCD-camera.

Intraframe (primary) processing:

  • loading of frames and series of frames with the same area of celestial sphere;
  • automatic deletion of defective pixels;
  • residual programmed frames adjustment using low-cut filter;
  • automatic division of frames series into subseries;
  • frames addition with accumulation of signals from moving object (FAMO) a type of frames addition used to increase signal/noise ratio (SNR) of signals from objects with unknown velocity of apparent motion;
  • formation and saving of total frames obtained with FAMO;
  • marking the signals of celestial objects on the frames;
  • evaluation of celestial objects coordinates (fitting) with compensation of residual backgrounds flat substrate;
  • making marks from selected objects.

Objects identification:

  • forming of inner catalog of objects that are motionless on the series of observation;
  • automatic identification of a sum of frames marks and inner catalog of motionless objects from series of observation with a stellar catalog;
  • automatic identification of asteroids tracks detected by the present software and known by MPC.

Astrometric and photometric frames reduction:

  • access to electronic stellar catalogs (USNO A2.0, USNO B1.0, UCAC 3.0 or XPM);
  • astrometric reduction of one out of three models of plate constants (linear, quadratic and cubic);
  • photometric reduction done through stellar catalogs USNO B1.0 or XPM.

Astrometric and photometric reduction assures accuracy that meets MPC requirements.

Interframe processing includes:

  • exclusion of inner catalog of objects with zero apparent motions marks from interframe processing;
  • asteroids detection by original algorithm of moving objects detection;
  • manual rejection of automatically detected asteroids; creation of MPC-report based on processing results.

Functions of built-in browser:

  • receiving data from MPC site about known asteroids and comets within the frames series range of vision;
  • comparison of formed measurements (marks) with MPC database; identification of known objects; decision-making as for the new objects detection;
  • NEO-rating receiving of detected objects;
  • coordinates determination of the frames center viewing field according to numbers and names of asteroids written in their titles;
  • creation of three similar MPC-reports based on results of processing series of frames for numbered, unnumbered and unknown asteroids (such reports can be made for each series and for all processed areas together).

Visualization:

  • review of initial and total files, formed and saved during FAMO;
  • display of detected objects, their marks, all marks of interframe processing, objects known by MPC.

Software characteristics:

  • creation of a log-file, containing output data through all stages and permitting to localize deficient and problem procedures of data processing;
  • automatic batch processing of all studying series of observation and results display;
  • paralleling of computings into independent processes according to the quantity of processors cores.

The software is divided into different executable modules which are connected through files. It represents the ideology of open architecture and permits to use independently created software at each stage of processing.
