Transient Detections and Other Real-Time Data Processing from MASTER-VWF Wide-Field Cameras
Figure 8
A image with a bolide. The black squares indicate objects extracted from the frame. The side of the square corresponds to the FWHM of the object. (a) shows a frame with objects extracted using standard SExtractor parameters (with the extraction threshold of ) with no filters applied. As a result, the program identified all Star-like objects, heaps of faint garbage, hot pixels, and simply random noise, that is, virtually everything except the bolide. (b) shows the result of extraction made using the currently adopted refined custom parameters. Several bright elongated objects are extracted on the bolide image and the noise level is appreciably lower.
