... 07/27/2004 Specifications: The GALFA Quadrature Downconverter Controller (QDC) interfaces the GALFA spectrometer computer and the analog QD boards. It is desired that for IF input levels between -25dBm to -10dBm, the output power from the analog QD is constant (about 0dBm). The GALFA spectrometer computer will sense the power level at the output, and using a DAC, it will adjust the gain on the analog QD board. ... Figure 2: MAX203 pin-out Fig. 3 shows the pin-out of MAX521 8-channel DAC. ...

... Finding Stars . ... Handling Bad Pixels . ... The guide camera image controller can control one or more guide cameras. ... Each time the camera is read, the image is automatically saved to a fits file on a shared disk. ... Cameras that have bad pixels require "bad pixel maps" in order to find stars, centroid or even compute statistics for the image. ... View this image (for instance in NIH Image) and determine an upper and lower cutoff; pixels whose values are outside of this range are considered...

. When you experience problems with your computer, you may need to email support (@stsci.edu). The help desk software will automatically respond with an email assigning a call number (example : CNSHD44674) to your problem. A more detailed email addressing your concern will be sent by the system personnel on call that day. Any follow-up email you send to system regarding the same issue must have this call number in the subject line.

... This relieves the rest of the computer from knowing how to use the drive, since the controllers for different types of disks can be made to use the same interface towards the rest of the computer. ... Usually the number of sectors is the same for all tracks, but some hard disks put more sectors in outer tracks (all sectors are of the same physical size, so more of them fit in the longer outer tracks). ... For example, a hard disk might have 8 heads, 2048 tracks, and 35 sectors per track . ...
