JWST-STScI-002267 SOCCER Entry 10/5/2010 `On' failures in the NIRSpec MEMS ST-ECF Instrument Science Report NGST 2002-02 The effects of `on' failures in a MEMS array for the NGST NIRSpec Santiago Arribas, Robert Fosbury Peter Jakobsen --1-- JWST-STScI-002267 SOCCER Entry 10/5/2010 ST-ECF Instrument Science Report NGST 2002-02 The effects of `on' failures in a MEMS array for the NGST ... From this, we can decide on an acceptable number of facet failures. ...

Next: Critical Frequencies and Gravitational Previous: Extragalactic Gravitational Wave Background . The number of binaries per frequency decade per solid angle from a separate stellar system (galaxy or cluster of galaxies) is . ... For example, for the Andromeda galaxy M31 ( rad, ) one gets . ... If the angular size of the galaxy is less than the angular resolution of the detector, the critical frequency is independent of the angular resolution, . ...

... We measured these galaxies individually, and they are distinguished in our list by the suffixes a, b, c,... in order of increasing J2000 right ascension. ... The first column contains the UGC catalog number, to which we have added lower-case suffixes a, b, c,\dots in order of increasing J2000 right ascension to distinguish individual galaxies in groups. ... The third column lists the degrees, arcminutes, and arcseconds of J2000 declination plus the rms uncertainty in arcseconds. ...
