... This value comes per quadrant and per CYCLEs: In case of full frame, extended full frame and large window modes NDISCLIN gives the number of discarded columns. The corresponding livetime factor is . ... The factor gives the number of active CCDs in the quadrant under consideration. ... In case of small window, timing, and burst mode there is only one active CCD. For these modes the onboard MIP rejection is switched off (all events transmitted, NDSCLIN = 0) and the equation reduces to . ...

... This paper describes a simple technique that cancels the DC offsets often found in Hubble Space Telescope's calibrated NICMOS images. ... Hubble Space Telescope NICMOS images often show quadrants with a slight mismatch in DC offset levels after the calibration process. ... Figure 1: NICMOS image showing DC offsets between quadrants. ... Figure: Same image depicted in Fig. 1 after being processed by the DC offset removal algorithm. ...

... 96.1655Garwood+ We presented results from a continuum VLA snapshot survey of the galactic plane in the longitude range 0d < l < 90d at 1.5 GHz. Observations were taken every 0.5^o in longitude at b=0^o. Most fields are complete to about 30 mJy peak density. The positions, peak, and total flux density of 471 compact sources (<30") have been measured. ...
