183. Towards Optimal Analysis of HST Crowded Stellar Fields
... The improvement will be more pronounced in our crowded Wide Field Camera (WFC) images, and may be increased further through use of a more sophisticated method of combining the individual dithered images. Our analysis allows us to check for point spread function shape variations in the HST Planetary Camera (PC) field. ... In crowded field images, we are deriving information about the faint end of the luminosity function (LF) from the texture of the image background. ...

... Configuring Depth 30 Displays . ... This driver release supports X screens with screen depths of 30 bits per pixel (10 bits per color component) on NVIDIA Quadro GPUs based on G80 and higher chip architectures. ... When displaying a depth 30 image, the color data may be dithered to lower bit depths, depending on the capabilities of the display device and how it is connected to the GPU. Some devices connected via analog VGA, DisplayPort, and HDMI can display the full 10 bit range of colors. ...
