1. Primary mirror supports
... In the case of the 2.5-m telescope primary mirror, the support actuators are air pistons. The 48 axial and 18 transverse air pistons support the axial and transverse components of the mirror weight vector respectively. ... Piston force . ... To measure the response of an air piston to transverse forces, a transverse piston was loaded with 11 kg lead bricks and pressurized using a syringe (Figure 3). ... Figure 4: The air piston acts like a spring with hysteresis in response to a side force. ...

3. Instrumental Properties
... Each Digicon diode has its own discriminator, and if they are properly set the dark count rate measured is very low. On-orbit measurement has shown that both GHRS detectors have a dark rate less than the design goal of 0.01 counts diode-1 sec-1 at low geomagnetic latitudes and that the dominant noise source is cosmic rays. ... Do not use CENSOR if the expected count rate exceeds about 100 counts per second per diode because real photon events will be rejected. ... Count Rate Linearity . ...

4. Why do Radiopulsars not Usually Form Pairs with Normal Stars?
Next: Caverns in Binary Systems Up: Ejectors in Massive Binary Previous: The Number of Ejectors . In the very first years after the discovery of radiopulsars, it became clear that for some reason they avoid forming binary systems. ... Illarionov and Sunyaev (1975)[ 76 ] noted the fact that coherent radiowaves with a wavelength longer than 75 cm, which make it possible to observe most of the radiopulsars, are absorbed effectively in the stellar wind of a normal star. ...

9. Geometric Correction
... An accurate two dimensional geometric correction over the entire frame is an important part of the whole reduction process. ... Logically, it often makes sense to separate the geometrical transformation into two orthogonal components: the dispersion relation , which can be obtained from an arc spectrum with a fully illuminated slit and the distortion along the slit , which can be derived from the continuum spectra of point sources. ...

11. Feature enhancement: normalizing
Next: Feature enhancement: local Up: No Title Previous: Feature enhancement: filtering . ... As a result, a common magnitude scale (contour lines on the maps above, or color scale on Fig.1) will poorly display the short-duration events in a signal. Normalizing each line of the map (fixed duration) so it has unit variance (in effect dividing the energy map by the mean energy spectrum) at each duration restores more details of small-scale activity (Fig. ...
