Convex chains for Schub ert varieties Valentina Kiritchenko (joint work with Evgeny Smirnov and Vladlen Timorin) In [4], we constructed generalized Newton polytopes for Schubert subvarieties in the variety of complete flags in Cn . Every such "polytope" is a union of faces of a Gelfand­Zetlin polytope (the latter is a well-known Newton­Okounkov body for the flag variety). ...

Position Switching Separation Tolerance with Arecibo in L-Band Travis McIntyre The University of New Mexico July 2010 Revised December 2013 Abstract The blocked telescope aperture at Arecibo creates standing waves in the bandpass around 1MHz. ... Test observations with Arecibo in L-Band show that position switching effectively removes standing waves for separations of one half FWHM or less. Standing waves remain for separations of one FWHM, increasing the rms of the baseline by 20%. ...

... The European HST Archive has been moved to ESA's European Space Astronomy Centre ( ESAC ), Spain, where most of ESA's Space Science Archives are located and operated from. ... The Space Telescope European Coordinating Facility (ST-ECF), jointly operated by ESA and the European Southern Observatory ( ESO ) was, until the end of 2010, the European HST science facility, supporting the European astronomy community in exploiting the research opportunities provided by the Hubble Space Telescope. ...

... This makes spatial event selection very hard of even impossible in cases where the object is too faint to clearly stand out against the X-ray background. movecalc takes an event table with aspect corrected X / Y coordinate columns (as generated by task attcalc ) and adds two new columns X_MOV / Y_MOV (different names can be specified via parameters xmovcol / ymovcol ) containing the corresponding coordinates in a reference frame that is centered on the moving object at all times. ...
