... At the operating temperature of -88 C, maintained after April 23, 1994, the WFPC2 CCDs have a low dark background, ranging between 0.002 and 0.01 e - /s/pixel. A relatively small number of pixels have dark currents many times the value. ... The combined file is obtained by using the superdark value for all pixels that appear normal in the weekly dark, namely, for which the dark current value in the weekly dark does not differ from the superdark value by more than 3 . ...

Next: Standard orientation Up: Preprocessing Previous: Bias correction . In a similar manner, long dark exposures of the same exposure time can be averaged to produce the DARK frames. ... Use the command COMPUTE/IMAGE to multiply the images by the exposure time and to add back the value for FLAT_BKG . ... Often, BIAS and DARK contain no large - scale structure. ... The commands AVERAGE/IMAGE and AVERAGE/WEIGHT offer number of options to compare the images and filter particle hits. ...

... There are compelling reasons for the pulsar community to utilise a standard data storage format. For example, standardisation of file formats significantly decreases the amount of effort required to integrate new instruments into the analysis chain. ... Accordingly, we have defined PSRFITS as a standard FITS-based format for pulsar data files. ... For example, the first line of Processing History HDU contains information about the data acquisition program and the initial structure of the file. ...

... During a magnetospheric substorm the cross-tail current is disrupted (e.g., Fairfield and Ness, 1970). A current system called the substorm current wedge (SCW; Atkinson, 1967; McPherron et al., 1973) is formed as this current is diverted through a circuit consisting of earthward (downward) field-aligned currents (FACs) on the eastern side of the wedge, a westward auroral electrojet in the ionosphere , and tailward (upward) FACs on the western side of the wedge. ...

Flare energy release in turbulent current sheet and particle acceleration in this system. ...

... New IRAF tools for the photometric calibration of optical/IR images are presented. The new tools are standard star catalog and world coordinate driven, requiring both accurate standard star catalog coordinate and accurate image coordinate data. Network access to standard star catalog servers is supported. ... The photometric calibration software will automatically convert the standard star coordinates from the standard star coordinate system to the image coordinate system. ...

... Here we address the issue of how to determine what calibration files make up the current calibration file for a given observation time. Each calibration file has a validity start date and a validity end date. ... In the simplest case (no end of validity date), a new version of the calibration file -- call it , will have and (figure 1 ). ... Within this scheme, at any time the applicable issue of the calibration file is obtained by selecting among all files the one with the higher issue number. ...
