  We present the atlas of protoplanetary disks in the Orion Nebula based on the
ACS/WFC images obtained for the HST Treasury Program on the Orion Nebula
Cluster. The observations have been carried out in 5 photometric filters nearly
equivalent to the standard B, V, Halpha, I, and z passbands. Our master catalog
lists 178 externally ionized proto-planetary disks (proplyds), 28 disks seen
only in absorption against the bright nebular background (silhouette disks), 8
disks seen only as dark lanes at the midplane of extended polar emission
(bipolar nebulae or reflection nebulae) and 5 sources showing jet emission with
no evidence of neither external ionized gas emission nor dark silhouette disks.
Many of these disks are associated with jets seen in Halpha and circumstellar
material detected through reflection emission in our broad-band filters;
approximately 2/3 have identified counterparts in x-rays. A total of 47 objects
(29 proplyds, 7 silhouette disks, 6 bipolar nebulae, 5 jets with no evidence of
proplyd emission or silhouette disk) are new detections with HST. We include in
our list 4 objects previously reported as circumstellar disks which have not
been detected in our HST/ACS images either because they are hidden by the
bleeding trails of a nearby saturated bright star or because of their location
out of the HST/ACS Treasury Program field. Other 31 sources previously reported
as extended objects do not harbor a stellar source in our HST/ACS images. We
also report on the detection of 16 red, elongated sources. Their location at
the edges of the field, far from the Trapezium Cluster core (> 10'), suggests
that these are probably background galaxies observed through low extinction
regions of the Orion Molecular Cloud OMC-1.
