... 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. ...
... Your main research interests concern dust. ... 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! ...

JSC Celebrates 40 Years of Human Space Flight . ... Scheduled for completion about 2006, the completed International Space Station will have a mass of about 1,040,000 pounds. ... The assembled space station will provide the first laboratory complex where gravity, a fundamental force on Earth, can be controlled for extended periods. ... Hospitals, business parks and solar electric power stations that beam clean, inexpensive energy back to Earth are likely to dot the "space-scape" 40 years from now. ...

... 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. ...

Once the plug-plate is assembled and installed on the telescope, guide stars imaged onto coherent fiber-optic bundles are used to determine the errors in telescope pointing, image scale and rotator angle. ... As described in the introduction, the holes are drilled tilted with respect to the normal to the plate surface. The tilt of holes were measured on six plates drilled prior to plate uw0111. ...
... We nd that in the 3-10 keV band EPIC MOS and PN spectral slopes are contained within a = 0:03, with the exception of the MOS1 measurement, which is found to be signi cantly atter. ... Clearly annuli including data 1 from the innermost regions are a ected by pile-up to some extent. ... Since the probability of an event to be lost to pile-up is independent of its energy, the loss of events will result in a lower normalization of the pattern 0 spectrum and not in a distortion of its shape. ...
