... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... The parameter pgdev allows the user to specify a pgplot device, but, in contrast to the pgplot standard, the file name should not be included, but instead supplied via the parameter plotfile . ... To write a colour postscript file called op.ps: pgdev=/cps plotfile=op.ps . However note that at present, if a colour postscript device ( pgdev = `/cps'), a fits file ( pgdev = `/fits') or a ppm file ( pgdev = `/ppm') are selected, the task in fact bypasses pgplot and writes the postscript file directly. ...

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. ...

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. ...

. The sharply-defined crater just above the center of this Cassini image shows layers of alternating bright and dark material. A thin dark layer on the crater wall appears to define the base of an ejecta blanket. Cassini was 8,314 miles (13,377 km) from Phoebe when this image was taken. NASA / JPL / CICLOPS

... We have developed graphics kernels for PyRAF written completely in Python that are capable of working with IRAF graphics tasks (including interactive tasks). ... We describe the design employed to isolate the details of IRAF's underlying graphics system from PyRAF, making it easier to support multiple kernels, including the ability to use the IRAF Graphics kernel tasks. ... The PyRAF interactive graphics kernel thus is written entirely in Python with no reuse of IRAF code. ...
