... APOD: 2007 February 20- White Ridges on Mars . ... Credit: HiRISE , MRO , LPL (U. Arizona) , NASA Explanation: What created these white ridges on Mars? The images showing the white ridges, including some of the highest resolution images ever taken from Martian orbit, were recorded last year by the Mars Reconnaissance Orbiter (MRO). A current leading hypothesis is that the white ridges formed as water flowed through underground cracks and bleached and hardened the edges of surrounding rocks. ...

. To create a file with the cat command: cat > memo remember to make appointment at opticians get cost of scheduled flight to Athens Ctrl-d .

This creates a file called tips in the current directory containing a single line of text.

... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment.

... This method effectively cuts the light curve at some number of sigma above the mean nominal level. One future ``method'' may include one that determines a fixed count rate plus some ``delta''. In this case, the high energy count rate, say 8-12 keV, is created and the user selects an appropriate threshold. ... The other future method performs a ratio screening which compares the count-rate per unit area in the obscured corners of the detector to the same in the FOV using the 8-12 keV band. ...
