STScI-PRC99-10 . ... Astronomers have used the NASA Hubble Space Telescope to produce an infrared "photo essay" of spiral galaxies. By penetrating the dust clouds swirling around the centers of these galaxies, the telescope’s infrared vision is offering fresh views of star birth. These six images, taken with the Near Infrared Camera and Multi-Object Spectrometer, showcase different views of spiral galaxies, from a face-on image of an entire galaxy to a close-up of a core. ...

... Plate bending . ... The plug-plates of SDSS project are responsible for locating the optical-fiber plugs spatially and for defining the plug tilt with respect to the surface of best focus. ... It can be seen from the graphs that after bending the plate and adding a central suport, the curvature of the plate was quite near that of the desired Kent005 curve. ... Upon adding a central support, however, the slope of the plate decreases to a value slightly less than that of the Kent005 curve. ...
