... Data . ... In general, Dolphin finds good agreement with the Whitmore, Heyer, and Casertano results, and the longer baseline and more extensive data set used by Dolphin result in less scatter in the residuals. ... In these case the Dolphin corrections are larger than the Whitmore et al. corrections. ... Figure 1 shows the ratio of counts from a 14 second exposure of Omega Cen in August, 2000 to the counts in a 100 second exposure, vs. the Y position on the chip (WF2 in this case with gain=15). ...

. There are several different shells available for Unix; the most popular are described here. You can use any one of these shells if they are available on your system. And you can switch between the different shells once you have found out if they are available. Bourne shell (sh) . C shell (csh) . TC shell (tcsh) . Korn shell (ksh) . Bourne Again SHell (bash) .

Next: Echelle Reduction Method Up: No Title Previous: Example . This Chapter provides the basic information necessary to understand the echelle љ package implemented in MIDAS . ... Tutorial examples are available in the system (command TUTORIAL/ECHELLE ) and are also included in the Appendix so that users without previous experience in MIDAS could become familiar with the calibration procedures. ... The methods described here are generally sufficient to cover a wide range of echelle formats. ...

Text copyright (c) 1997. ... We study the X-ray spectra of 114 flat-spectrum radio quasars (FSRQ) using the hardness ratios as given in the WGA catalogue of ROSAT sources. ... We find that FSRQ have a distribution of energy spectral indices ranging between 0 and 3 with a mean value alpha_x ~ 1. ... Figure 1 (13kb) . ...

... As with all tutorials, this document describes detailed steps to just one particular effect. ... Create a new Greyscale image, and put some text in it. ... Duplicate U1, then run Gaussian blur 5.00. ... Then, invert the image so it is white on black. ... Multiply U2 and U3. ... Invert U1, so it is white text on black background. ... Then run Gaussian Blur 4.00. ... If you like you can multiply this by a texture, for a textured background, but for this tutorial the background is white. ...

... As an experiment, I made some three-color images of Messier 42, more commonly known as the Great Nebula of Orion. ... green enhanced . ... halfsize or fullsize . ... Each image is a ``true color'' composite of three monochromatic images, in which the red, green, and blue intensities each correspond to the intensity of one of the original images. ... The HST image is assembled from different filters than mine: red is Nitrogen [II] at 6583 , green is H-alpha at 6563 , and blue is O [III] at 5007 . ...

... Einstein data for SNR are available as images on magnetic tape or diskette and as tables of counting rates. ... In seven cases, with coverage from 35% to 90%, we have calculated an HRI rate for the entire SNR by using the observed IPC data and assuming the ratio of HRI to IPC rates was the same for the observed and the unobserved parts of the remnant. ... Positions of the bright bulge sources and remnants in the galactic plane are known and the rates in table 2 are free of the effects of these. ...

... VLBI Schedule . ... LBA log files for Tsys, onsource flagging etc are available in a number of different forms, unfortunately with each telescope being supplied in a different way. ... All logfiles should be accessible via the experiment wiki or the experiment ftp area (which is linked to from the wiki) . Tsys and onsource flagging should be available suitable for AIPS (in UVFLG and ANTAB form) on the experiment ftp area. ... Tsys monitoring logs are also available from the experiment wiki. ...
