Development of computational method for detection of the object’s near-zero apparent motion on the series of ccd-frames

Development and Improvements of Computational Methods Implemented to the Colitec Software

“…It has been used in about 700 000 observations, during which four comets C/2011 X1 (Elenin), P/2011 NO1 (Elenin), C/2012 S1 (ISON) and P/2013 V3 (Nevski) out of seven discovered in the CIS and the Baltic States over the past 20 years were identified using CoLiTec. In total, the CoLiTec software was used for discovery more than 1560 asteroids, including 5 NEO, 21 Trojan asteroids of Jupiter and 1 Centaur (see, also, Savanevych et al, 2012Savanevych et al, , 2018Khlamov et al, 2016Khlamov et al, , 2017Vavilova et al, 2012Vavilova et al, , 2017Vavilova, 2016).…”

“…The detection of objects with the near-zero apparent motion is performed by the method, which is based on the significance verification of the speed factor of object (Khlamov et al, 2016). Fisher F-criterion is used as significance criterion in this method.…”

Virtual Observatory and Colitec Software: Modules, Features, Methods

“…Considerable achievements of the CoLiTec software are associated with the detection of objects with near-zero apparent motion. For example, at the time of discovery, the image size of the comet C 2012 S1(ISON) was 5 pixels, and it shifted by 3 pixels for 4 frames (Khlamov et al, 2016). The Centaur 2013 UL10 was shifted by 10 pixels with the image size of 4-5 pixels at the time of discovery.…”

New algorithm for astrometric reduction of the wide-field images

“…Therefore, the authors suggest also using the statistical criterions, such as Student t-criterion or Fisher f-criterion, instead of using the maximum likelihood criterion, as in the works [7,8].…”
