Errata 2004

 

Time-Scales, Section B

  • Page B30, example of stellar reduction, Step 2, EB, the time derivative of EB, and SB were taken from the JPL DE200/LE200, rather than the DE405/LE405 barycentric ephemeris. However, this did not affect the final apparent place.

The Sun, Section C

  • Page C1, Eccentricity of the Sun:

    for 0.016 691 82 - 0.000 000 0115 d, read 0.016 706 95 - 0.000 000 0012 d.

Major Planets, Section E

  • Page E43, semidiameter at unit distance for Pluto:

    for 2.07, read 1.65.

Satellites of the Planets, Section F

  • Page F6, Diagram title:

    for “Apparent Orbits of the Satellites at Opposition, July 1,”
    delete “at Opposition.” There is no opposition of Mars in 2004.

  • Page F59, missing greatest northern elongations of Miranda:

    for April 2: 03.0h UT and for August 27: 02.8h UT

Stars and Stellar Systems, Section H

  • Table of Bright Stars, orbital correction to positions of wide binaries was incorrectly applied to the Hipparchos positions:

    BS=HR No. 5459

    replace 14h 39m 55.5" -60° 51' 06" by 14h 39m 55.0" -60° 51' 09"

    BS=HR No. 5460

    replace 14h 39m 53.0" -60° 51' 23" by 14h 39m 53.6" -60° 51' 19"

    (For stars BS=HR No. 5459 and BS=HR No. 5460, these errata also apply to the Table of Double Stars.)

    BS=HR No. 8085

    replace 21h 07m 05.4" +38° 46' 31" by 21h 07m 06.1" +38° 46' 18"

    BS=HR No. 8086

    replace 21h 07m 08.0" +38° 45' 37" by 21h 07m 07.4" +38° 45' 51"
