Pulkovo NEO Page . ... NEA Accuracy Estimation . ... The estimation of accuracy of the current CCD observations of asteroids and comets is constantly performed at Pulkovo Observatory. ... The (O-C) values, so called "Observed" minus "Calculated" positions, characterize numerically the observations of any observatory, both professional and amateur, during a short period (one or several close nights). ... So the (O-C) values for these objects nearly entirely define the errors of observations. ...

... The exact directions of the offsets are parallel to the rows and columns of the CCD on which the aperture is specified. ...

Examples of pipeline processing . ... This page presents examples of "on the fly" processing of FITS astronomical data available on the WEB using the HyperLeda pipeline tools. ... In many cases, raw data are archived and a consisten description of the file (FITS header) allows to process them on the fly. ... This first command makes a "pre-view" display of the image. o=fa:L93111HP1/00147&z=vg . ... The result of a pipeline processing is a FITS file that you can read as a normal disk file. ...

The geocentric angular distance between magnetic footprints of two satellites in the same time is considered as a criterion of the magnetic conjugations. The situation is identified, as a magnetic conjugation in case as the relative angular distance of the mentioned magnetic footprints is less then 5 deg. ... The output file with name 'xy.cng' contains the information about X and Y satellites magnetic conjugations as a function of the Universal time. ... See the output file description ...

... Next: Cheating Poisson: A Up: Statistical Analysis Previous: Spatial Models and . ... The spatial distribution of stars in the Local Group dwarf irregular galaxy NGC 6822 has been studied, using recent positions and deep photometry for about 15,000 stars in the galaxy. Based on photometrical data, OB stars and red stars could be studied separately. Spatial statistical tools have been applied to the analysis of the spatial structure. ... Figure: Model selection by the aid of CAIC . ...

Region markers can be moved, resized, rotated, zoomed, deleted, and can change geometric type. ... For example, markers placed on astronomical catalog positions should be fixed so that one cannot accidentally move them off the specified position. ... Parameters can be fixed using the fix option of the regions public access point (for fixing classes of markers) or by means of a fix keyword in the definition of an externally loaded marker. ... In the command: echo "regions fix all -position -size" | ...

fitcircle - find mean position and pole of best-fit great [or small] circle to points on a sphere. fitcircle [ xyfile ] -L norm [ -H [ nrec ] ] [ -S ] [ -V ] [ -: ] [ -bi [ s ][ n ] ] fitcircle reads lon,lat [or lat,lon] values from the first two columns on standard input [or xyfile ]. ... Then two locations are found: the mean of the input positions, and the pole to the great circle which best fits the input positions. ... If no file is specified, fitcircle will read from standard input. ...

For example, the designations of objects in the list can occupy the last position in each line. ...

Posit ion switched data can be converted from spectrometer counts to kelvins using the cal values (see cnts to kelvins ). ... CalInK(avg) is the measured cal value averaged over the entire 172 Mhz band of the spectra. ... The mask was then applied to all averages. the 1200 Mhz polB is not on scale, but it is offset from the 1350 Mhz band . Bottom: Compute the rfi mask from the calon,off and well as the position on,off data. the 1200 Mhz band now has a smaller offset from the 1350 Band. ...
