... There are 6 different analysis options: . 0:all : all the exposures corresponding to the chosen observation are reduced to calibrated event lists, unless disabled via the corresponding parameter ( PN , MOS , RGS , OM , all set to "yes" by default). ... The EPIC data is then searched for source detections, via edetect_chain . By default, for the EPIC data, if more than one exposure is present, these actions are taken over the event list corresponding to the longest observation. ...

From a study of three HeI lines, the rotational velocity of the star was determined as km/s. After five years of spectroscopic monitoring of IGR J06074+2205 (Reig et al. 2010), a reversion from emission to absorption of the H line and hence disappearance of the equatorial disk was reported. ...

ON THE IMPACT OF THE GALACTIC ABERRATION ON VLBI-DERIVED PRECESSION MODEL Z.M. MALKIN Pulkovo Observatory Pulkovskoe Ch. ... Corrections to adopted precession rate are usually computed from the linear trends in long-term time series of celestial pole offset (CPO), which are the differences between the measured and the theoretical coordinates of the celestial pole. ... CONCLUSIONS We have estimated the impact of GA on parameters of precession-nutation model derived from VLBI observations. ...
