Here we describe two ad hoc methods of combining single-dish and mosaic images. ... where and are the beam volumes of the synthesised mosaic beam and the single-dish beam respectively). ... If both the interferometer primary beam and the single-dish beam are gaussian forms with widths and respectively, then you will want to add a gaussian to the mosaic beam dataset which has a width . ...

Next: Sky Subtraction Up: Construction of Flat Previous: Standard construction . For a number of projects where very deep integrations and accurate flat fields are required, and the targets are point sources or much smaller than the frame size, the sky background itself can be used to calculate the flat field. ... Use STATISTICS/IMAGE to calculate the image median, and COMPUTE/IMAGE to divide by this to get the normalised flat field. ...

Blackholes Forum Message . Forums: . ... Alternative Idea . ...

... We have been upgrading the software front-end to WASP (Wideband Autocorrelating SPectrometer, operating from 800 to 4000 MHz) from Lynx-OS to Real-Time Linux and will discuss Real-Time software aspects. We are using a standard parallel ``PIO'' card to receive data from the spectrometer and standard GPIB interfaces that drive a frequency synthesizer for bandpass calibration. WASP and its front-end computer are fully mobile and can be taken to any suitable radio telescope. ...

Instrument Science Report NICMOS-98-010 NICMOS Parallel Thermal Background: Results from SMOV and Cycle 7. ... Parallel observations in NICMOS Camera 2 and Camera 3 are taken at different pointings and analysis of the data shows the HST thermal emission to be fairly stable, with an orbital variation of ~5% and a secular variation of ~8%. ... In this study, the thermal background measurements are presented as the average count-rate calculated over the entire chip. ...

Possibility of existence of life based on biochemical processes different from typical for Earth living organisms is discussing. ... They can be organisms used absolutely different material bases and solvents (i.e. methane life) and living under different physical and chemical conditions (temperature, medium composition)/ These organisms are rather often examining in literature. ...

... The large body of near infrared observations presented in Testi et al. (1997; 1998) are analysed with the aim of characterizing the young stellar clusters surrounding Herbig Ae/Be stars. The results confirm the tendency of early Be stars to be surrounded by dense clusters of lower mass "companions", while Ae stars are never found to be associated with conspicuous groups. ... Only the most massive stars (10-20Msun) are found to be associated with dense (10^3 pc^-3) stellar clusters. ...

We inform the variable-star community that the publication of the "Peremennye Zvezdy" (Variable Stars) journal, founded by Prof. B.V. Kukarkin (1909 1977) in 1928, is planned to be resumed by November, 2005. Currently it is possible for us to publish "Peremennye Zvezdy" only as an electronic journal. ... The main journal will accept original scientific papers containing theoretical results as well as results based on detailed analysis of variable-star observations. ...

... I normally begin by asking the class what they think would be different if the Moon didn't exist, or if the Sun were closer to Earth, or if a star exploded nearby. ... The winds would be much stronger. ... In using what-if questions in the classroom, it is worth bearing in mind that students extrapolating the effects of new scenarios will encounter two different situations: direct changes to the new version of Earth and indirect changes resulting from the direct changes. ...

... For a semple of red giants comprising about 2000 stars, the distributions of metallicity [Fe/H] are given. ... The center of the distributions of giants in both galactic poles is found to demonstate a statisticaly significant gap similar to the one found earlier for the late main-sequence stars. The implications of the metallicity distribution properties for the problems of the chemical evolution of the galactic disk are discussed. ...

SN 1989B Light Curve Analysis. ... In the light curve depicting their observations, definite trends are noted, here is a "thumb-nail" analysis of the the magnitude estimations of the bright SN (1989B) in the galaxy NGC 3627 (M66). ... The observations were inserted against the V magnitude templete of BL, CCD photometric data, (Wells et. al, (1994) and a color trend (B-V) histogram of the mean type Ia SN (BL)(nutemp.gif).

Next: Introduction . ... A spike immunity method of digital integrating radiometer signals in the jamming environment is described. ... The purpose of the method is real-time signal processing, and the basic is an alternative selection of the least offset signal estimation using nonparametric "Nearest Neighbor" rule. ... The additive spike-like jam makes the "tails" of the distribution "heavier" which leads to different offsets for linear and rank mean estimation on the integrating interval. ...

... Early on, our interest in chirping analysis functions was motivated by a different kind of chirping phenomenon: chirping due to perspective. ... Our interest in radar, however, drew us toward processes that are more accurately analyzed by linear-FM chirplets. ... We have also constructed other chirplet transforms, such as a three-parameter Doppler chirplet representation that models a source producing a sinusoidal wave, while moving along a straight line (e.g. a train whistle). ...

In October last year I made the tough decision to leave astronomy, after 11 years and 4 postdocs in three different countries. ... In this talk I will describe my journey from academia to industry, outline what a day in my life as a data scientist is like, and discuss the outlook for data science over the next few years. I will also suggest how someone from an astronomy background can best prepare themselves for a similar transition into data science. ...
