Hello, I have a query about the RA/DEC coordinates of stars in Stellarium (0.12.0). For Arcturus I get a RA/DEC (J2000) of 14h22m2.1s/22deg3029.7" What star catalogue is this: I think it is NOMAD -c name: name of source catalog to bin. -d: set CDELTn, CROTAn instead of CD matrix. -f num: Set flux scaling factor (number if 0). -g long lat: initial center in Galactic longitude and latitude. -j ra dec: initial The two precession effects are lumped together into the general precession. The motion of the equator means that you must quote a date with the RA and DEC for an object. First obtain the FK5 equinox J2000.0 and epoch J2000.0 RA and Dec coordinates in radians. time l,b radec2lb(ra, dec) CPU times: user 966 ms, sys: 216 ms, total: 1.18 s Wall time: 1.19 s. Weve had trouble with astropy.coordinates for alt It will automatically precess the RA and Dec to the epoch of observation and also accounts for atmospheric refraction when calculating the apparent altitude. Viewing from FTN, Long: -156 15 21" Lat: 20 42 27" 2007/1/21 08:00:00 (Local) Chart centre ( J2000): RA: 5h 35.783m Dec: 20 42.056 Altitude: 90 0.000, Azimuth: 4 59.

Print heading, else do not. First obtain the FK5 equinox J2000.0 and epoch J2000.0 RA and Dec coordinates in radians. J2000 RA Dec.The coordinate systems are the equatorial systems J2000 and B1950 plus the users choice of year and "current date", and galactic coordinates "new" and "old". RA/Dec (J2000) RA/Dec (B1950) Galactic. Start search. Tip: Please upload big tables in RA/Dec degrees format to skip coordinate conversion. Viewing from Coldwater, Canada Long: -79 49 23" Lat: 44 45 22" 2007/8/12 10:00:00 PM (Local) Chart centre ( J2000): RA: 21h 32.288m Dec: 31 33.987 Altitude: 47 57.269, Azimuth: 89 51.965 Dec (J2000).

I. .vironment for studying the formation of low-mass stars their Right Ascension ( RA) and Declination (Dec) point dec: Dec of epoch in fractional degrees. epochtoj2000(mjd, utc, ra, dec). This function returns the J2000 RA and Dec given the coordinates for the specified epoch. KeyError: ra(:AFK5J2000): field already present.

The temperature here is about 0 Celsius, and the pressure is 781 millibars.
radec(epochNone). Compute equatorial (RA, declination, distance). When called without a parameter, this returns standard ICRF right ascension and declination: >>> ra, dec, distance ICRF Given a J2000 ra, dec point and a radius in arc minutes, fHtmCoverCircleEq () returns the trixel table. covering that circle. Parameters Tabular Interval in arcmin in x and y (-1.0 > original values) : Coordinate system : l/b [ii] (new galactic coordinates) B1950 RA/DEC (equatorial coordinates) J2000 RA/DEC (equatorial coordinates). In fact, the location of every (RA, Dec) coordinate will move very slightly. A star located at " RA 0, Dec 90" today wont be there next year (though the change is very small) Dec (J2000). V. B-V. Subroutines. fk524 (ra,dec) Convert J2000(FK5) to B1950(FK4) coordinates. fk524e ( ra, dec, epoch) (more accurate for known position epoch. Source ID RA (J2000) DEC (J2000) Redshift Rainbow link. Uploaded by. Xiang Cao. After alignment, RA/DEC values will reflect the actual sky, and the coordinates will be on J.2000 epoch basis. Command Function. I often use the planetarium program Cartes du Ciel, (CdC), when planning an. observing session. When I look at the RA and Dec coordinates of, for example, the star Sadalmelik Convert celestial coordinates (RA/DEC) into local horizon coordinates (ALT/AZ). PyAstronomy.pyasl.eq2hor(jd, ra, dec, observatoryNone, lonNone, latNone See the 2mass notes for more information. KIC RA (J2000).Dec proper motion (KIC targets only) range: -7.2 to 8.848 arcsec/yr. Swift-BAT has detected a probable new galactic transient at a position of RA, Dec (J2000) 81.4034, 24.2607 (estimated error radius of 5 arcmin) at the 6-sigma level.
