Again, this is compatible with the explanation provided for X14H0203T. X14H0302T, X14H0303T, and X14H0304T At roughly 220 seconds into the observation X14H0302T, a disturbance resulted in a ~1.65" shift of the sub-dominant GS (see Fig. ...

... In this paper, a project aiming to allow access to data archives by means of a query-by-example mechanism is described.

Next: Functionality Up: RGS_EXAFS Previous: RGS_EXAFS Contents . EXAFS means Extended X-ray Absorption Fine Structure. This CCF describes the detailed absorption lengths of different layers of CCDs in the vicinity of absoption edges to facilitate accurate calculation of quantum efficiencies. Away from the edges, the well-known Henke coefficients are used. There are two notable RGS instrumental absorption features by oxygen and fluorine. ... Michael Smith 2011-09-20 ...

Text of report The subject if our report is the influence of the structure and physics of the uppermost superadaibatic layers on the oscillational spectrum of p-modes. ... In our report we will try to use a most simple representation of the spectrum, plotting the differences between theoretical (that is models') and observational frequencies against a frequency. ... It allow us to focused on the effects of the uppermost layers and ignore possible sophistications from effect of more deeper layers. ...

... Between them, the following points are touched: ICRF-2 structure, ICRF Core sources selection, and some expected user's requirements. ... Suggested total number of sources is close to the number of sources already observed in the IVS and VCS sessions, and for most of them reliable positions are derived, mostly for declination > -40 deg. ... So, results of source position time series analysis heavily depend on method used for time series computation and should be used with care. ...

... The Taurid meteor shower occurs every year, when the Earth passes through the Taurid meteoroid complex , a huge stream of material orbiting in interplanetary space. ... Calculations were based on the dates Nov 3 (pre-perihelion) and Jun 23 (post-perihelion); in fact, the swarm spans a week to each side of these dates (and the entire Taurid stream is even broader than the swarm). Negative Delta M means the swarm centre (resonance centre) is short of the Earth at the Jun or Nov date in question. ...

Since the light from galaxies represents the integrated contribution of its consitutient stars, then we can learn about stellar populations in galaxies by modelling their light by summing up individual stellar spectra for different kinds of stars. ...
