... The various Inst :Focus scripts allow you to take a series of exposures over a range of secondary mirror focus values, report the resulting FWHMs and optionally adjust the focus to the estimated best value. ... Slitviewer scripts assume the focus star is on the boresight. ... Focus scripts runs in three phases: . ... The script moves the boresight so the focus star is visible next to the slit, sets the focus to Center Focus, takes an exposure and tries to measure the star's FWHM. ...

The basic characteristics of the instrument are set by the aperture, focal length and resolution of the image forming lens, the dispersion of the spectrometer, and the sensitivity of the detector. ... The lens is internally focused, and maintains acceptable focus (2 pixels in the detector plane) over a typical spectral coverage of one grating setting. ... along the spatial dimension of a 25mm square detector in the final spectral image plane the 400mm lens is 3.2њ. ...

... Any channels not specified will be set to the same frequency as the first. ... Whenever the frequencies change, a comment appears in the operator schedule file; the appropriate changes are made to the BBC frequencies for antennas using VLBA or VEX control files; and for snap files, dummy video converter commands are written without the correct video converter number and with the full LO sum (personnel at ``snap'' sites must edit in the correct video converter numbers and subtract the first LO). ...

Optical Filters . ... In addition to the above complement of broad and narrow-band filters, WFPC2 features a set of three specialized quadrant (quad or Q) filters in which each quadrant corresponds to a facet of the pyramid, and therefore to a distinct camera relay. ... In Table 3.1 and Table 3.2 , each of the type "A" filters is equivalent to inserting 5 mm of quartz in terms of optical path length, with compensation for wavelength such that focus is maintained on the CCDs. ...

... Drag data has the following properties: . Drag action type (ie GDK_ACTION_COPY, GDK_ACTION_MOVE). ... A GDK_ACTION_COPY would be a typical drag-and-drop without the source data being deleted while GDK_ACTION_MOVE would be just like GDK_ACTION_COPY but the source data will be 'suggested' to be deleted after the received signal handler is called. ... Sent and received data format types ( selection target ) come into play only in your request and received data handler functions. ...
