VII/57 List of Globules (Wesselius 1979)
================================================================================
List of Globules Based on 7 Lists by Wesselius
Wesselius P.R.
<private communication (1979)>
================================================================================
ADC_Keywords: Interstellar dust
Description:
Wesselius compiled this list based on seven lists. The main list is
one in preparation in Australia supplied by Miller Goss, a second list
obtained from Bok that he referred to as the Catalog of Southern
Globules, Hartley-Manchester Catalog (1978), and five other lists from
Bok and Cordwell (1973), Martin and Barrett (1978), Bok, Cordwell, and
MacCarthy (1974), and Sim (1968a, 1968b). Wesselius notes that this
list is not complete in any sense. The fields in the catalog are:
running number (1-821), name of globule, B1950.0 positions, position
in galactic coordinates, approximate angular size, and reference.

Note on Name:
Wesselius' globules list was based on 7 lists:
The main list is one prepared in Australia. He originally got a preliminary
printout of Miller Goss (Ref. 1).
In end 1978 a list that Bok had in his possession while visiting Groningen
(Ref. 2). Wesselius referred to it as: the Catalog of Southern Globules,
Hartley-Manchester Catalog; this version was presented to Bok in October
1978 as a computer printout.
The other lists used were:
3. Bok, B. J.,Cordwell, C.S.;1973; "Molecules in the Galactic Environment",
edited by M.A. Gordon and E. Snyder (New York; John Wiley and Sons
Inc.), p. 82-86.
4. Martin, R.W., Barrett, A.H.;1978, Ap.J. Suppl. 36, p. 4.
5. Bok, B.J., Cordwell MacCarthy, C.; 1974, Astron. J.79, 43.
6. Sim, M. E.; 1968, Publications of the Royal Observatory, Edinburgh,
Vol.6, No.8, p. 191-194.
7. Idem as 6, p. 196-198.
This list of globules was not complete. For the southern sky a
preliminary list concerning part of the sky was used. For the northern sky
the only overall list available was that of B.T. Lynds of dark nebulae, but
this covers in general larger dark regions than globules, and was not
incorporated in the list (Wesselius, private communication).
Note on SizeRA, SizeDEC:
Approximate angular size (this field is blank in 20 records)
Note on ref:
For the numbered list of references, see bytes 6-19 above.
Remarks and Modifications:
This catalogue was received at NASA/Goddard Space Flight Center (GSFC) on
magnetic tape from P. R. Wesselius, Laboratorium voor Ruimteonderzoek,
Rijksuniversiteit, Groningen, The Netherlands, in February 1980. The data
given were not edited or altered at GSFC, but the following information was
added:
sequential number of record (bytes 1-4)
new galactic coordinates (bytes 38-52)
The logical record length was decreased from 80 bytes to 66 bytes through
the removal of blanks.
For references, see bytes 6-19.
