... Tiny Tim has been used for generating Hubble Space Telescope ( HST ) point-spread functions (PSFs) for deconvolution, algorithm testing, proposal planning, and optical studies. ... Tiny Tim is a stand-alone program for simulating HST PSFs as viewed with the on-board imaging cameras (WF/PC-1, WFPC2, FOC, COSTAR/FOC). ... The measured aberrations for FOC f/96, WF/PC-1 PC6, WFPC2, and COSTAR/FOC are used by Tiny Tim . ... Figure: FOC f/96 observed and Tiny Tim model PSFs (pre-COSTAR) at 253 nm. ...

... One characteristic of the ATCA dishes is that they are big by 3-mm standards. Indeed van Hoerner (1967) has considered the limits to the size of an antenna before various effects become significant. ... As the ATCA dishes are twice this, it is not surprise that the ATCA antenna gain and primary beam response varies as a result of thermal distortions. ... A gain/elevation correction will solve this - to first order at least. ... This might be an important effect for widefield imaging and mosaicing. ...

... The WFPC2 CCDs have a small b ut significant charge transfer efficiency (CTE) problem which causes some signal to be lost when charge is transferred down the chip during readout. This has the effect of making objects at higher row numbers (more charge transfers) appear fainter than they would if they were at low row numbers. The effect depends on the temperature of the CCDs. ... It is also possible that proportional losses for fainter stars, at least with no background, may be larger. ...

In Appendix A, the axial force balance equation at the horizon was shown to be . ... The quantity that we really wish to derive is , where is the rod elongation at some initial epoch (i.e. when the rods were first tensioned) and where is the rod elongation at some later time after the rod temperatures had changed. ...

In addition, extensive DSP effect functions are includes to give you complete control of your computer sound output. 32-note polyphony enables your system to produce all types of music production, sound effects and quality background music. ...

... Unlike clients such as Shout and IceDJ this permits the broadcast of live audio, rather than prerecorded mp3's. LiveIce was developed after the appearance of IceCast to provide the Real Time streaming functionality which makes it a viable solution for broadcasting. It is based on the guts of 2 of my previous works - Mp3Serv, the first mp3 broadcasting system & Mp3Mixer, a toy which allows the user to 'Mix' with mp3 streams. ... LiveIce XMMS sourcecode is available here . ...

... In the first page of this chapter, Eddington computes an effective temperature of 3.18 K, but this has nothing to do with the 2.725 K blackbody spectrum of the Cosmic Microwave Background (CMB) . Here is a quote of what Eddington actually said: . ... We shall first calculate the energy density of this radiation. ... It is clear that Eddington's model fits the optical data, but that Eddington did not anticipate either the CMB (red curve) or the interstellar dust (ISD, green curve). ...
