2. Fast search through RTT150 data archive
RTT150 . ... This search system is designed for generating the necessary information on series of pointings (observations of each source consist of sets of exposures with different filters and sometimes with different exposure times) for observed sources. Search results appear at the separate page as a table with the following data: . DATE - real (not evening!) observations date (in YYYY-MM-DD format); . ... Bin - minimal CCD binning mode (may vary during the observations); . ...

3. TUI:Scripts:Built In Scripts:Telescope:Pointing Data
The Telescope:Pointing Data script takes set of pointing error measurements of pointing reference stars across the sky. ... To retry measuring the star, fix the problem (e.g. by adjusting focus, exposure time or offset) and press Continue . ... For each point in the az/alt grid the script will find and slew to a nearby pointing reference star, measure the star, write the pointing error to a data file whose path is displayed, and correct the pointing error. ...

4. sep11 calibration after installation.
... the alfa calibration results (.ps) ( .pdf ): . the pointing error vs rotation angle offset (.ps) ( .pdf ): . ... Comparing the two lets you separate out the alfa installation errors with general telescope pointing problems (from the beam repair). ... Part of the pointing error could come from the alfa rotation angle being off. ... Compute the change in the pointing error if the alfa rotation error was off by -5 to +5 degrees in .1 degree steps. ... Top: rms pointing error vs rotation angle offset. ...

5. IDL programs
... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...

... It is found that the correlation coefficients between these two parameters calculated separately inside and outside the sunspot formation zone ±30 have cyclic variation and occur in anti-phase. This suggests different mechanisms of formation of the corona in the fields of small, medium, and large scales. ... The relationship between the coronal green line brightness (CGLB) and the magnetic field strength (MFS) has been investigated by constructing the corresponding synoptic maps for the 1977-2001. ...

7. Alternative construction
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. ...

8. APOD: 2011 March 24 - Boston Moonrise
... 2011 March 24 . Boston Moonrise . ... Explanation: Last week's Full Moon was hard to miss . Rising on March 19, its exact full phase occurred within an hour of perigee, the closest point in the Moon's orbit to Earth. As a result it appeared some 14 percent larger and 30 percent brighter than a Full Moon near apogee, the most distant point in the elliptical lunar orbit. ... If you managed to miss this perigee Full Moon, make a note on your calendar. ... About APOD | ...

... NGC 7129 and NGC 7142 . ... This alluring telescopic image looks toward the constellation Cepheus and an intriguing visual pairing of dusty reflection nebula NGC 7129 (left) and open star cluster NGC 7142. The two appear separated by only half a degree on the sky, but they actually lie at quite different distances. ... Tethys, one of Saturn's larger moons at about 1000 kilometers in diameter, survived the collision, but sports today the expansive impact crater Odysseus. ... August . ...

... Neutral hydrogen is the best tracer of accreting and outflowing gas, however very hard to detect due to its low column density. ... Simulations predict that in order to detect HI in the extended environment of galaxies, brightness sensitivities well below NHI ~1018 cm-2 are required (e.g. Popping et al. ... Direct aims of the projects include: - Achieve a 1 sigma NHI of 2.5x1017 cm-2 over 20 km/s. - Measure the extended gas content of galaxies to detect gas accretion and outflows. ...

Microsymposium 38, MS083, 2003 (A4 format) MERCURY: LOCAL VARIATIONS OF THE PHOTOMETRIC RELIEF. ... Because of trajectory and pointing angle constraints the planet could be observed from Mariner 10 only over a small range of phase angles between about 75o and 110o. Therefore the photometric investigations are restricted to measuring the distribution of brightness on the Mercurian disk. ... Raw versions of real-time processing pictures FDS 0000984 and FDS 0000986 were used (images 196 and 202). ...
