| Four monochromatic (H{dollar}alpha{dollar}, (N II), (O III) and 5500 A continuum) mosaics of the inner region of the Orion Nebula have been made by using data obtained with the Wide Field Planetary Camera 2 of the Hubble Space Telescope. These mosaics have a common area of {dollar}7spprime52sp{lcub}primeprime{rcub} times 9spprime25sp{lcub}primeprime{rcub}{dollar} which is the largest area of the Orion Nebula covered by the Hubble Space Telescope images in a single study.; Making use of these Wide Field Planetary Camera 2 data, a survey of compact sources and stars down to V {dollar}approx{dollar} 22 has been done. A total of 489 sources that are not Herbig-Haro objects have been found. 145 of them can be classified as protoplanetary disks (proplyds).; The proplyds have been classified into eight different forms. The forms which show strong evidence of interaction with a stellar force are concentrated near {dollar}Thetasp1{dollar}C Ori. Those forms that do not show such evidence are more widely spread. |
