Target Acquisition Reference Information . Figure 7.1 on page 88 shows mean predicted count rates as a function of (B - V) 0 color for the four acquisition mirrors. Also shown are the fits to the predicted count rates for different amounts of reddening. ... You can estimate target acquisition count rates using the plots instead of Table 7.1 on page 92 : . ... Read from the Figures (depending on the mirror used) the predicted count rate. ...

... This calibration approach is recommended when dealing with high frequency data from the old ATCA correlator, especially at 3mm wavelengths. ... The approach described here exploits the dual frequency bands that were available with the old correlator. ... Rather the current approach assumes that you have a single Miriad dataset containing bandpass calibrator, phase calibrator, flux density calibrator and program source. ... MFCAL . ...

Calibration mode that scans 4 times across the calibrator, forming a spider shape. ... Calibration mode that scans twice across the calibrator, forming a cross shape. ... This is the standard spectral-line single-pixel observing mode. ... A Calibration mode used by the Galactic ALFA surveys to calibration the G-ALFA HI Spectrometer. ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

... galaxies . ... Hubble rules out one alternative to dark energy . ... Astronomers using NASA's Hubble Space Telescope have ruled out an alternate theory on the nature of dark energy after recalculating the expansion rate of the universe to unprecedented accuracy. ... The Hubble observations were conducted by the Supernova Ho for the Equation of State (SHOES) team that works to refine the accuracy of the Hubble constant to a precision that allows for a better characterization of dark energy's behavior...

XMM­Newton CCF Release Note XMM­CCF­REL­228 pn modified Timing mode response matrix M. Kirsch July 10, 2007 1 Purpose Using the EPIC­pn CCD camera in Timing mode, in which data are read out continuously, telemetry constraints do not allow full use of the capabilities for very bright sources because currently randomly distributed data gaps are introduced by the on­board data handling electronics. ... Lower: same but using the new modified matrix for the modified Timing mode (red). ...

Next: Sky Subtraction Up: Construction of Flat Previous: Standard construction . For a number of projects where very deep integrations and accurate flat fields are required, and the targets are point sources or much smaller than the frame size, the sky background itself can be used to calculate the flat field. ... Use STATISTICS/IMAGE to calculate the image median, and COMPUTE/IMAGE to divide by this to get the normalised flat field. ...

... Editor's note: Since other stars are so far away, much of the progress we are making in understanding stars in general comes from studying our own "hometown'' star, the Sun. ... We must begin with an important warning: Never look directly at the Sun, especially when using binoculars or a telescope. ... Any specks on the image of the Sun which do not jiggle along with the image when you do this are specks in the binoculars or telescope (or smudges on the screen), and not spots on the Sun itself. ...

... AstroCC is a coordinate conversion utility for astronomy. It accepts an object designation or the coordinates of an object and calculates coordinates in alternative systems, and at different dates, times, and locations. It also provides lunar and bright planet coordinates to aid in planning observations. ... BJD values may also be retrieved from http://astroutils.astronomy.ohio-state.edu/time/utc2bjd.html which is based on Eastman et al. ... Coordinate data are obtained from SIMBAD. ...
