We find that the FUV-MAMA has improved resolving power (at the cost of sensitivity) when the repeller-wire high-voltage is turned off. ... To fully realize the increase in resolution provided by this mode, users will have to reprocess the data on their own using the CALSTIS package in STSDAS with parameters set for HiRes pixels. ...

... December 21, 1997 . ... Advantages are briefly discussed of gaining in spectral resolution, which is accompanied by losses in signal level, as compared with the attempts to improve the accuracy of measurement of line parameters by means of rising the S/N ratio alone with increasing the exposure time. To partially solve the problem of observations of faint objects at the BTA a new design echelle spectrometer is proposed. high resolution spectroscopy . ...

... Data was taken with lbw and the mock spectrometers on 05may09 to investigate the problem with higher time resolution and bandwidth. ... 6 172 Mhz bands were taken centered at: 1200,1300,1400,1500,1600, and 1700 Mhz. 8192 channels (20Khz resolution) was used for the low time resolution (.1 second dumps). 4096 channels (40Khz resolution) was used for the high time resolution (.001 second dumps). ... The total power was computed for each 172 Mhz band and then plotted vs time (.1 second resolution). ...

Chiaki Kobayashi, Ralph Sutherland How galaxies did form and evolution? - to answer this unsolved problem, we are simulating the formation and evolutionary history of galaxies in the Universe, including star formation, supernovae feedback, and chemical enrichment. Comparing the spacial distribution of elements within galaxies with observations, we will examine fundamental physical processes that drive galaxy formation. ...

A most promising problem is to investigate the interaction of two VHF powerful radiowave beams in the ionosphere, whose difference frequency is equal to the plasma frequency in some ionospheric area (that is, the difference frequency is taken in the range 1-8 MHz). ... Two-frequency interaction effects are based on radiowave non-linear mixing, which is rather complicated when describing and modelling the experiment. ...

... Please note the following problems and workarounds: . ... Arrow keys . Arrow keys are used in SAOtng to move the mouse or markers. ... Unfortunately, error messages are generated if both sets are defined in the SAOtng code but are not supported by X. To get around this problem, we have added the -kbprefix command switch (and the SAOTNG_KBPREFIX environment variable) to SAOtng. This switch allows you to specify which arrow keys you want to use (assuming your version of X supports both). ...
