... 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 . ...

... With the drain current = 11mamps, the Tsys was about 90 K. A 12 db amp was placed after the dewar to increase the power level. ... On 10oct11 dana used the expensive spectrum analyzer to verify that the standard Tsys measurements on bm4a were correct. He did this with the 12db amp inserted and then with the 16db amp. ... The mocks measure Tsys12= 52.9 and Tsys16=62.3K. You would expect the 16db amp to have a "better Tsys" than the 12db amp since the power is still low for the 12db amp. ...

The threshold value is currently a slider/text field pair which have a precision of .0001. ... Like the Threshold value, the Flare Intensity has both a slider and a text input field for specifying its value. ...

... 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. ...

Next: Modes of Operation Up: CCD Scientific Performance Previous: Field of View . Thermal excitation of charge carriers from the valence to the conduction band creates a dark current signal which may vary with position in the array, and also has temporal shot noise variation. ... In a device devoid of localized defects which give rise to individual dark current spikes , most dark current arises from electrons generated at interface states at the surface. ...

... Note: This has not been updated since changes were made in the block device interface to support block device loadable modules. ... To mount a filesystem on a device, it must be a block device driven by a block device driver. ... Instead, your driver uses block_read() and block_write() , which are generic functions, provided by the VFS, which will call the strategy routine, or request() function, which you write in place of read() and write() for your driver. ... DEVICE_NAME is simply the device...
