Flat Fields for the Ccd Spectral Modes
Except for fringing effects at the longer wavelengths, the pixel-to-pixel flat field for the spectral modes is independent of wavelength but does change with time. An average flat with one to four million electrons/px is applicable to all CCD first order modes, except G750M, after the dust mote regions are inserted from separate low or medium dispersion flats. Application of this flat to spectr...
متن کاملA Technique for Ultrahigh-Precision CCD Photometry
We present techniques for wide-field ultrahigh-precision time-sampled CCD photometry. Representing a survey of field stars, our data consist of UBVRI photometry and a V-band time series of exposures on 5 consecutive nights covering 11,500 stars in a ∼1 deg field. The resulting light curves reach precisions of 0.0020 mag per exposure in the brightest stars ( ). Light curves binned and averaged o...
متن کاملIs Daycare Tonsillectomy Safe?
Introduction: Tonsillectomy is one of the most common procedures performed by Ear, Nose, and Throat surgeon. Usually, the procedure is carried out as an inpatient surgery. With the increasing need to reduce healthcare costs, spare precious hospital beds, and shorten elective surgery lists, there is currently a trend towards performing tonsillectomy on a daycare basis. Materials and Methods: A...
متن کاملWhen every $P$-flat ideal is flat
In this paper, we study the class of rings in which every $P$-flat ideal is flat and which will be called $PFF$-rings. In particular, Von Neumann regular rings, hereditary rings, semi-hereditary ring, PID and arithmetical rings are examples of $PFF$-rings. In the context domain, this notion coincide with Pr"{u}fer domain. We provide necessary and sufficient conditions for...
متن کاملBuilding a CCD Spectrograph for Educational or Amateur Astronomy
We discuss the design of an inexpensive, high-throughput CCD spectrograph for a small telescope. By using optical fibers to carry the light from the telescope focus to a table-top spectrograph, one can minimize the weight carried by the telescope and simplify the spectrograph design. We recently employed this approach in the construction of IntroSpec, an instrument built for the 16-inch Knowles...
