Summary0001542: Incorrect position for PN K 4-8 in GPN
DescriptionSimbad gives the following positions for PN K 4-8:
18 54 20.01 -08 47 33.3 (J2000)
18 51 36.13 -08 51 22.9 (B1950)
See http://simbad.u-strasbg.fr/simbad/sim-id?Ident=PN+K+4-8&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id

And Kohoutek's original paper listing this object gives the following position for it:
18 51 36.1 -08 51 22 (B1950)
See No 8 of Table 4 on page 3 of this PDF:
http://cdsads.u-strasbg.fr/cgi-bin/nph-iarticle_query?1965BAICz..16..221K&data_type=PDF_HIGH&whole_paper=YES&type=PRINTER&filetype=.pdf

However, the position for this object shown in Skychart, after enabling the Strasbourg-ESO Catalog of Galactic Planetary Nebulae, is this:
18 54 20.0 -08 53 32 (J2000)
Notice that it is approximately six arcminutes too far south.

A PDF of Part I the GPN can be accessed here:
http://adsabs.harvard.edu/cgi-bin/nph-data_query?link_type=ARTICLE&url=http%3a//www.eso.org/sci/libraries/historicaldocuments/Strasbourg-ESO%5fcatalogue/Strasbourg-ESO%5fCatalogue%5fof%5fGalactical%5fPlanetary%5fNebulae%5fPart%5fI.pdf&bibcode=1992secg.book.....A&db_key=AST
The finder chart on page 149 (page 150 of the PDF) shows the correct location, but the position given in the table on page 28 (page 32 of the PDF) is incorrect.

So it appears to be an error in the original catalog, and the Skychart catalog is faithfully reproducing that error. Nevertheless, I think it would be good to fix this so the correct position is shown.
Additional InformationI am using version skychart-data-dso 3.8-2293.
TagsNo tags attached.

Yes, probably a typo, -08 57 22 instead of -08 51 22.

There is another errata in the ftp directory: ftp://cdsarc.u-strasbg.fr/pub/cats/V/84/errata.txt

I will correct that.
