... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

Pulkovo NEO Page . ... EPOS Software Package . ... EPOS ( E phemeris P rogram for O bjects of the S olar system) is the Windows PC application for study and ephemeris support of observations of the Solar system objects. ... It controls the part of common data and transfers the control to one of the programs that solve the restricted set of tasks. ... So with the EPOS software package one can calculate the accurate ephemerides for many objects and get the quick illustration of their motion as well. ...

... This task operates on event data in an event list. ... In the first two cases, the celestial coordinates of the reference point are taken respectively as the values of the RA_NOM , DEC_NOM or RA_OBJ , DEC_OBJ values in the input event file header. ... Although the OM attitude information may be more accurate, it will not be present throughout part of the observation, and as such, the default source for the attitude data should be "ahf". ...

New reduction of minor planets photographic plates obtained with Pulkovo Normal Astrograph A.A. Berezhnoy Pulkovo Observatory of RAS, Saint-Petersburg, Russia Minor Planet observations at Pulkovo Periodical observations of 14 bright asteroids named Selected Minor Planets (SMP) were performed at Pulkovo since 1948 within the international framework started by works of B.V. Numerov and D. Brouwer. ... 108 133 113 74 124 67 97 88 14 84 64 5 20 19 Epochs (YYYY.MM) 1200 Mean values of total obs. ...

The position of the objects on the sky were generally measured to a precision between 1 and 4 arcsec. ... For the stars, the position is always at epoch 2000, whatever J2000 or B1950 coordinates are printed. ... The celestial position is given as coordinates in 4 different systems: . ... B1950 . ... Galactic coordinates in the reference frame called "new" system, adopted by IAU in 1958. Galactic pole at B124900.0+272400, node at ra=282.25,l=33 deg (inclination 62.6 deg). ... 1 arcsec . ...

Observatory Support . ... The science header keyword ORIENTAT is populated by adding the angle between the HST V3 axis and the detector Y axis to what we will call the "commanded roll" (North to V3 through East). The V3-detY angles that were relevant at a given observation's epoch are given as a header keyword (beta_2) in the Observation Log files (aka jitter files). ... The commanded roll and the jitter file's ROLL_AVG should agree to within 0.05 degrees, usually better than 0.02deg. ...

Below you can read the latest Announcements from the European ARC Network.. ... The call for 1-mm Very Long Baseline Interferometry (VLBI) proposals to use phased ALMA at Band 6 in Cycle 4, in collaboration with the Event Horizon Telescope Consortium (EHTC), will be released to coincide with the ALMA Cycle 4 Call for Proposals in March 2016...

Next: Program use Up: Description of program searchdup Previous: Description of program searchdup . Parameter input is done with a graphic user interface. ... Input file: Name of the input catalog file. It has to be formatted, one record per source/observation, according to the format used in the Arcetri observations and source archives. ... Minimum number of observations per source Source with less than this number of independent observations are not included in the output file . ...

Top panel: comparison between the observed H and H line profile (black solid line) and synthetic profiles calculated with the final adopted parameters (dash-dotted green line) and with the parameters which were found to best fit the hydrogen line profiles (dashed red line). ... We provide photometric and spectroscopic evidence showing the star is most likely a member of the young Stock 16 open cluster (age 3тАУ8 Myr). ...

... There is an opportunity to perform O-C calculations for objects which are absent in the data base of the package. Such objects can be described by orbital elements or by initial coordinates and velocities. ... On pressing Edit file button user has a possibility to look through the list of object elements or their coordinates and velocities to add or to change it. ... For example, the designations of objects in the list can occupy the last position in each line. ...
