Abstract:
We present the atlas of protoplanetary disks in the Orion Nebula based
on the Wide Field Channel of the Advanced Camera for Surveys (ACS/WFC)
images obtained for the Hubble Space Telescope (HST) Treasury Program
on the Orion Nebula Cluster. The observations have been carried out in
five photometric filters nearly equivalent to the standard B, V,
Hα, I, and z passbands. Our master catalog lists 178 externally
ionized protoplanetary disks (proplyds), 28 disks seen only in
absorption against the bright nebular background (silhouette disks),
eight disks seen only as dark lanes at the midplane of extended polar
emission (bipolar nebulae or reflection nebulae), and five sources
showing jet emission with no evidence of either external ionized gas
emission or dark silhouette disks.
Description:
The images have been extracted from the large dataset (520 images) of
ACS/WFC observations executed between 2004 November and 2005 April.
The ACS/WFC survey has covered an area of about 450arcmin2, centered
about 4' southwest of the Trapezium cluster.
In data subdirectory, every file name has the structure:
object name+"_"+filter+".fits", where object name is the name of the
object as reported in the paper and filter is the HST/ACS photometric
filter of the image. These images are astrometrically correct, i.e.
field distortion has been removed. The fits headers contain the
correct astrometric information (WCS) and return absolutely calibrated
coordinates.
In these drizzled images the pixel values are in counts per second,
and an estimate in magnitudes of the photometry of a source can be
directly extracted by m=-2.5Log(F)+ZP, where m is the magnitude of the
source in the passband of interest, F is the observed flux of the
source in counts per second in that passband, and ZP is the passband
zero-point magnitude in a certain photometric system. In the paper,
Table 2 lists the zero-point magnitudes derived by the Photometric
Calibration of the HST/ACS camera (Sirianni et al.,
2005PASP..117.1049S 2005PASP..117.1049S) in the VEGAMAG, ABMAG and STMAG standard
photometric systems for the filters used by our survey.
