Если ледяные планеты происходят из комет на периферии Солнечной системы за последней планетой-гигантом Нептуном, то астероиды происходят из комет вблизи Солнца, ближе первой из планет-гигантов Юпитера. ...
... I was in the process of writing on ?model uncertainty? to understand why the same term is used differently in astronomy and in statistics and planned to include some papers to show how statisticians handle uncertainty. ... Draper used the O-ring data set, one of the most frequently cited data sets in statistics textbooks. ... One of my favorite statisticians is John Tukey , of Fast Fourier Transform, higher criticisms, and exploratory data analysis which are all well known to astronomers. ...

One of your main pleasures in life is going to conferences, and asking the question `have you considered dust obscuration?' after every talk by an optical astronomer, and watching their embarrassed evasions. ... Just look at any starburst galaxy: they are the most luminous objects in the local universe, but they are so dusty that the optical astronomers never even noticed them until the infra-red astronomers pointed them out! ...

... The process of proposing for Hubble Space Telescope observing time has been revised, to make it simpler for proposers. We describe the simple, flexible, and robust prototype system created to handle proposal submission. ... Proposing for Hubble Space Telescope ( HST ) observing time proceeds in two phases: the scientific merits of the proposal are considered in Phase I; only accepted proposals enter Phase II, where the observations are described in complete detail. ...
... The HSL Algorithm for Reducing NICMOS Polarimetry Observations . ... The preflight Thermal Vacuum tests revealed that each polarizer has a unique polarizing efficiency, and that the position angle offsets differ from the nominal positions of 0, 120 & 240. ... I also present estimates of the NICMOS Instrumental Polarization, and discuss both the sensitivity of the Grisms to polarized light and the accuracy of NICMOS imaging polarimetry for faint and low polarization objects. ...
... We examine the effects of amplifiers gain fluctuations, of fluctuations in the amplifiers noise temperatures, in the reference load tem perature and in the DC gain ratio. We find that 1=f gain fluctuations are suppressed by proper gain modulation, leaving fluctuations in the amplifiers noise temperatures as the main source of 1=f type noise. ... 4 Discussion and conclusions We have shown that the dominant source of 1=f noise in the radiometer output is amplifier noise temperature fluctuations. ...
