HIIREGION Catalog
This database table is derived from data contained in the Sharpless Catalogue
of H II regions. The original catalog was published in 1959 in the Astrophysical
Journal Supplement Series (number 41, pages 257- 280). The original card deck
was in the 026 punch and this was converted to a 029 deck. Many of the
quantities in this version of the catalog were not in the published
catalog. The epochs of the precessed equatorial coordinates were determined
empirically from the data as given on the computer cards.
LBN Catalog
The Lynds' Catalog of Bright Nebulae lists the coordinates of the center of
the cloud, the dimensions of the nebulae as measured on the photograph on which
it appeared at its brightest, the area of nebulosity in square degrees, color
as compared between the blue and red Palomar plates, a brightness index on a
scale from 1 to 6, an identification number that indicates the complexity of
the nebulosity, and a cross reference to NGC (Cat. <VII.1>), Index Catalogue
(IC), Sharpless (1959) Catalogue of HII Regions (Cat. <VII/20>), Cederblad
(1956) Catalogue of Diffuse Galactic Nebulae, and Dorschner and Gurtler
(1963).
LDN Catalog
This catalog is an updated version of the original version of the
Lynds' Catalog of Dark Nebulae that was published in 1962. The
catalog was based on a study of the red and blue prints of the
National Geographic - Palomar Observatory Sky Atlas. The catalog
contains positions for the centers of dark nebulae or clouds found
by Lynds, values for the cloud sizes in square degrees, visual
estimates of their opacity, and cross-identifications to Barnard
Objects which are associated with the tabulated clouds.
LMCEXTOBJ Catalog
A survey of extended objects in the Large Magellanic Cloud (LMC)
was carried out on the ESO/SERC R and J Sky Survey Atlases, checking entries
in previous catalogs and searching for new objects. The census provided
6659 objects including star clusters, emission-free associations, and
objects related to emission nebulae. Each of these classes contains
three subclasses with intermediate properties, which are used to infer
total populations. The survey includes cross-identifications among
catalogs, and includes 3246 new objects (~49% of the unified catalog). The
authors have provided accurate positions, classification, and homogeneous
measurements of sizes and position angles, as well as information on cluster
pairs and hierarchical relation for superimposed objects. This unification and
enlargement of catalogs is important for future searches of fainter
and smaller new objects. The present catalog together with its
previous counterpart for the SMC and the inter-Cloud region provide a
total population of 7847 extended objects in the Magellanic System.
The angular distribution of the ensemble reveals important clues on
the interaction between the LMC and SMC.
MASHPNCAT Catalog
The first part of the Macquarie/AAO/Strasbourg H-alpha Planetary Nebula
Catalog (MASH) contains 903 new true, likely and possible Galactic planetary
nebulae (PNe) discovered in the AAO/UKST H-alpha survey of the southern
Galactic Plane. The combination of depth, resolution, uniformity, and areal
coverage of the H-alpha survey has opened up an hitherto unexplored region
of parameter space permitting the detection of this significant new PN sample.
The second part, MASH-II, consists of over 300 true, likely and possible
new Galactic PNe found after re-examination of the entire AAO/UKST H-alpha
survey of the Southern Galactic Plane in digital form. Over 240 of these
new candidates were confirmed as bona fide PNe on the basis of spectroscopic
observations.
This HEASARC table contains all 1238 objects from the combined MASH and
MASH-II catalogs.
MOSTSNRCAT Catalog
A catalog of supernova remnants (SNR) in the southern Galaxy within
the Galactic Plane area 245 degrees <= galactic longitude l_II <= 355 degrees,
galactic latitude |b_II| <~ 1.5 degrees has been produced from observations
made in a series of 650 overlapping fields at 0.843 GHz (35.6 cm) with a
spatial resolution of 43" using the Molonglo Observatory Synthesis Telescope
(MOST). This table contains information on 57 known SNR (listed in Table MSC.A
of the reference paper), 18 SNR newly discovered in this survey (Table MSC.B),
16 possible SNR (Table MSC.C), and 2 reclassified SNR (discussed in Section 3.3
of the reference paper), for a total of 93 SNR.
MWP1BUBBLE Catalog
This table contains a new catalog of 5106 infrared bubbles created through
visual classification via the online citizen science website 'The Milky Way
Project' (MWP). Bubbles in the new catalog have been independently measured
by at least five individuals, producing consensus parameters for their
positions, radii, thicknesses, eccentricities and position angles. Citizen
scientists - volunteers recruited online and taking part in this research -
have independently rediscovered the locations of at least 86% of three widely
used catalogs of bubbles and H II regions while finding an order of magnitude
more objects. 29% of the bubbles in the Milky Way Project catalog lie on the
rim of a larger bubble, or have smaller bubbles located within them, opening
up the possibility of better statistical studies of triggered star formation.
This online resource of the Milky Way Project
provides a crowd-sourced map of bubbles and arcs in the Milky Way, and will
enable better statistical analysis of Galactic star formation sites. This
table is the first data release of the MWP IR Bubble Catalog: the authors
anticipate a future release of a second, refined catalog incorporating better
data-reduction techniques.
PLNEBULAE Catalog
This is the 1992 Version of the Strasbourg-ESO Catalog of Galactic
Planetary Nebulae (Acker et al.1992). It includes 1143 true and probable
planetary nebulae (from Table 1 of the publication) and 347 objects whose
status was still unclear and were thus classified among the "possible"
planetary nebulae (from Table 2 of the publication); it does not include
330 objects once considered as possible planetary nebulae but which the
authors have since rejected (listed in Table 3 of the publication).
The designation system for the planetary nebulae listed in this catalog
follows the recommendations of IAU Commission 5 (Astronomical Nomenclature)
with the structure: "PN Glll.l+bb.b", where PN means "Planetary Nebula", G
stands for "Galactic Coordinates", and lll.l+bb.b are the galactic longitude
and latitude respectively, truncated to one decimal place.
Copies of the complete catalog, including the Finding Charts (Part I) can
be ordered from the ESO Information Service, Karl-Schwarzschildstr. 2,
D-85748 Garching bei Muenchen, Germany.
REFNEBULAE Catalog
Several catalogs of reflection nebulae have been merged to create
a uniform catalog of 913 objects. It contains revised coordinates,
cross-identifications of nebulae and stars, as well as identifications
with IRAS point sources.
The HEASARC has endeavored to render all identifications of the nebulae in
the various catalogs according to the styles recommended by the Dictionary
of Nomenclature of Celestial Objects.
SNRGREEN Catalog
This catalog of known Galactic supernova remnants (SNRs) is an updated
version of the catalogs of Galactic SNRs presented in detail in Green (1984,
1988), in summary form in Green (1991, 1996, 2004, 2009), and on the Web
(versions of 1995-July, 1996-August, 1998-September, 2000-August,
2001-December, 2004-January, 2006-April, 2009-March, and 2014-May).
[Note that the version published in Green (1996) was produced in 1993.]
This June 2017 version of the catalog contains 295 SNRs, and is based on
results published in the literature up to the end of 2016. The basic summary
data included in this catalog for each SNR are its designation, position,
angular size (in arcminutes), type, flux density at 1 GHz, spectral index,
and any other names by which it is known. Notes on these parameters, on
possible remnants not included, and on questionable SNRs that are listed in
this catalog, are given in the full version of the catalog on the Web at
http://www.mrao.cam.ac.uk/surveys/snrs/snrs.info.html
It should be noted that there are serious selection effects which apply to
the identification of Galactic SNRs (e.g., Green 1991, 2004, 2005, 2009,
2014), so that care should be taken if these data are used in any statistical
studies.
