... The 6075 program is unique in its manner of obtaining data, and there is not an analogous set of observations to which to compare. However, there are some ways of seeing if similar effects are seen in similar circumstances. ... Examination of the details of that program showed that the same spectrum (at 2000 , say) was obtained in very different parts of an orbit during different executions of the monitor. ... Whatever is causing the Gilliland effect does not appear to be tied to orbital phasing. ...

The zero assumption often made is that the mass ratio distribution has a flat shape, that is binaries with a high mass ratio occur as frequently as those with equal masses. ...

CIMA configuration files offer You a conveniant way of saving CIMA set-ups to files. ... Then instead of making this selections interactively when You are observing, You can just load and apply the configuration files. ... Any other set-up will be ignored! ... In that case, You are forced to use the 'Load only' option to load the configuration file, inspect the selected set-up carefully, apply the set-up (with the 'Accept' or 'Apply' buttons) and then save a new version of the configuration file. ...

... A theory suggests that a certain sub-class of gamma-ray bursts all have the same absolute magnitude. ... The author claims that this absolute magnitude is so different from that in the previous sample that this must belong to a new sub-class of gamma-ray bursts. ... To do this, there needs to be some feature in their spectra which correlates with their absolute magnitude. ... Consider a telescope which is continually monitoring a star, looking for transits due to planets orbiting this star. ...
