DIGITAL WDC EXCHANGE FORMAT . FOR OBSERVATORY 1.0 MINUTE VALUES 1. ... DATA-1 .. DATA-60 are 1-minute values of the given element for that hour. ... Typically, digital 1-minute values received by WDCs from organizations operating automatic magnetic observatory instruments are averages of more frequendy sampled values, e.g. 10-second point samples. ... If the method used to obtain 1-minute average values is important to a user, the WDC will assist in determining the exact procedure applied. ...

Output connection: UDP jumbo packets (one packet per VDIF frame) over 10G IP links Receiver architecture is based on a parallel polyphase filter bank, dividing the input band into 32 overlapping bands of 256 MHz each. ...

... This noise can be reduced by replacing the pixels with an average of the surrounding values using a linear filter. ... The effects of applying linear filters to a CCD frame is shown in Figure . Figure: Different digital filters applied on a CCD image: (A) original, (B) block filter, (C) smooth filter, and (D) Laplacian filter. ... To remove stellar images from a picture of comet Halley, the results of applying different non--linear filters to the frame are given in Figure . ...

... Each spectrographic cartridge consists of 32 fiber bundles, with 20 fibers per bundle. Each bundle of fibers is clamped below the plate (in sky orientation) by an aluminum anchor block. The fiber emerges from this anchor block with heavy jacketing and is terminated with a precision ferrule which is plugged into a hole on the plate. The reach of a fiber is determined by the point at which it emerges from the anchor block. ...
