Next: Imaging Polarimetry with NICMOS Up: NICMOS Data Calibration and Previous: The Photometric Performance of . ... NICMOSlook and Calnic C . ... Extracting spectra from a large number of NICMOS grism images requires a convenient interactive tool which allows a user to manipulate direct/grism image pairs. ... NICMOSlook and Calnic-C are two programs that were designed to take advantage of the fact that the NICMOS grism mode typically consists of taking both a direct and a grism image. ...

In 1950 Jan Oort noticed that . no comet has been observed with an orbit that indicates that it came from interstellar space, . ... From this he proposed that comets reside in a vast cloud at the outer reaches of the solar system. ... Unfortunately, since the individual comets are so small and at such large distances, we have no direct evidence about the Oort Cloud. ... Its orbit is intermediate between the Kuiper Belt and what was previously thought to be the inner part of the Oort Cloud. ...

The eyes can be exposed to a variety of hazards, such as flying objects (from hand tools or other equipment), small particles (grinding wheels), dusts, splashes of corrosive liquids or metals, injurious lights or heat rays, and poisonous gas fumes. ... Persons who wear corrective eyeglasses can wear mono-goggles over the corrective glasses or safety over glasses. Complete eye protection on certain jobs, such as machining operations, call for the use of side shields on safety glasses. ...

... Tour Objects Tours can be created using objects from within the Autostar database or a user can enter in different objects (such as a newly discovered comet). ... Automatic Mode: As the user advances to each object, the title of the object appears on line 1 of the display while its descriptive text automatically starts scrolling across line 2. ... For example: STAR "Rigel" LANDMARK az alt "title" "description" Enter the azimuth (az) for the desired object in the following format xxxdxxmxxs. ...

Appendix E. Dots Per Inch . ... DPI (Dots Per Inch), also known as PPI (Pixels Per Inch), is a property of an X screen that describes the physical size of pixels. Some X applications, such as xterm, can use the DPI of an X screen to determine how large (in pixels) to draw an object in order for that object to be displayed at the desired physical size on the display device. ... The NVIDIA X driver reports the size of the X screen in pixels and in millimeters. ... grep -B1 dot . ...

... The BL Lac objects found within DXRBS fall mostly in the range . ... A large fraction of the BL Lacs so far in our sample are at L X / L R < 10 -6.5 , the region of Figure 6 populated by LBLs. In this region of parameter space (to the left of the left-most dashed line in Figure 6), DXRBS includes objects up to two orders of magnitude fainter than the 1 Jy survey. ... For comparison, we have plotted the values for members of these three ROSAT-based surveys (DXRBS, HQS/RASS and RC) in Figure 7. ...

... Events . ... Occultations by Kuiper Belt Objects . ... Thursday, Jun 11, 2009 at 8:00 PM . A stellar occultation occurs when a solar system body passes between a star and an observer. ... The atmospheres of the major planets, three of the four planetary ring systems, and numerous asteroids have been probed with stellar occultations. ... With stellar occultation data we can also probe for close companions and possible tenuous atmospheres. ... Copyright (c) Amateur Telescope Makers of Boston, Inc. ...

The Status popup displays useful information about the state of sets, regions, and graphs. ... When the number of sets is less than 30, this button is not needed, use the scroll bars to view the status of the sets that are not shown in the display. ... Operations in the Status popup are performed by clicking on the operation, then clicking on one or more set numbers shown in the display. ... Clicking on Copy followed by clicking on a set number in the scrolled window will select the set to copy from. ...

DISCLAIMER: The larger the aperture, the more light a telescope will gather and the fainter the object you can see. Here is a range of magnitudes you might expect to see. Given excellent sky conditions and good optics, a well trained eye can sometimes add up to 0.8 magnitude to these values. Limiting Magnitude depends on much more than the instruments aperture. ... One formula is for aperture in inches the other is for aperture in millimeters. ... Aperture (inches) . ... 15.2 . ...

A descriptor , also commonly called a file handle is an object that a program uses to read or write an open file, or open network socket, or a variety of other devices. ... The operating system enforces a limit on the number of descriptors that a program can have open at a time. ... One is a kernel limitation, depending on your operating system you will either be able to tune the number of descriptors available to higher numbers (this is frequently called FD_SETSIZE ). ...

... High-resolution Near-infrared Study of the Deeply Embedded Young Stellar Object S140 IRS 3 . ... P22P We explore the structures immediately surrounding the high-mass young stellar object S140 IRS 3 within the L1204 molecular cloud. ... The S-shaped structure of this feature can be well reproduced by a model assuming a precessing outflow from IRS 3a. Furthermore, we find several elongated features pointing away from IRS 3 in a southern direction. ...
