... Our Galaxy . Milky Way . ... Universe . ... Space Flight . ... Other galaxies are not moving away because they are recoiling in disgust from the Milky Way, but appear to be receding because the Universe is expanding. ... Observers in any galaxy will see every other galaxy as redshifted, so there is nothing special about the Milky Way. ... If the Universe is expanding today, that implies that in the past the galaxies would have been closer together and the Universe was much smaller than it is now. ...

SciSim home . ... This thread contains a step-by-step recipe to simulate MOS SciSim data and how to procede to analyze this data using SAS. ... For tcsh shell execute: source $SCISIM_DIR/setup . ... In this example, we are explaining how to proceed in order to run a MOS simulation, so we have to load the Telescope-1 default configuration, if we want to simulate MOS1 and RGS1. ... Select the Source menu and the Edit... option. ... To create a source, hit the New button at the bottom dialogue. ...

... ARC 3.5m | NICFPS . ... Taking Exposures . ... As with other IR detectors, it has the capability to be read out non-destructively, allowing for multiple readouts per exposure. In NICFPS, the number of times the detector is read out for each exposure is determined by the Fowler Sampling (FS or NFS, Number of Fowler Samples) setting. ... The NFS=0 mode is somewhat unusual for an IR detector; in this mode, the array is reset, the specified exposure time elapses, and then the detector is read out. ...
