... They are the offset in arcseconds for the x and y inst plane offset, the exposure time in seconds, and the number of exposures at each position. ... A point about offsets should be made here. The dither program uses absolute instrument plane offsets, so you should use object plane offsets to center up on the chip so that the script starts from where you centered up. INST and OBJ offsets are independent so an object offset will not be zeroed out by and inst plane offset, just added to it. ...

Linear frequency modulated continuous signals sounding method is relatively simple and has wide application in various special-purpose systems. ... Chirp signals which are applying for ionosphere channel diagnostics usually have10KHz/s -- 1MHz/s. We must point out that under modulation speed increasing there is an increase in noise suppression and resolution power. ...
