That is done by creating a Calibration Index File ( CIF ) which will tell our reduction processes which CCF s we need to use out of all available in SAS_CCFPATH , for the specific date of our observation data. ...

... The measurements themselves should be stored in a column with the label SIGNAL. ... Programs will expect that SIGNAL represents the integration of the photon flux for the exposure time given in the EXPTIME column (see section ). ... In that case, the column label should be RAWMAG; see Table . Programs will expect RAWMAG to be the usual negative logarithms of intensities; that is, RAWMAG values only use EXPTIME in determining weights. ...

... Figure 23: Binary pulsar fractions among the total number of pulsars   as a function of the mean kick velocity for a maxwellian distribution   (left-hand panel) and that fitting Lyne and Lorimer's data (right-hand panel). ... Therefore, the observed diversity and number of binary pulsars, while requiring a small kick velocity ( 100-150 km s ) to be present, are, at the same time, in strong contradiction with the presently derived high mean transverse velocities of pulsars. ...

In a game of ping-pong, suppose a paddle moves at 20 miles per hour and hits a ball with 20 mph in the opposite direction. ... In the new problem, a ball moving at -40 mph hits a non-moving surface; if the collision is elastic (no energy lost), that ball returns with the same speed but in the opposite direction, i.e. its velocity reverses sign. ... Something very similar happens when a spacecraft with velocity v passes close to a moving planet and is deflected. ...
