. This is the first one I have actually out and out missed. I had even checked it against a second generation DSS scan and just decided it was a non-symetrical nucleus. The estimated magnitude is about 15.7. Mike Schwartz , Director . Tenagra Observatories, Ltd. Cottage Grove, OR 97424 . Back to Bright Supernovae . Back to Supernova 1999an .

For example, modified Newtonian dynamics (MOND) has no relativistic extension, and so makes no firm lensing predictions, but galaxy-galaxy lensing data can be used to empirically constrain the deflection law of a MONDian point-mass. ...

The Astronomical Society of Australia has been asked by STANDARDS AUSTRALIA to compile a list of "designated" optical observatories that are valuable resources for (i) research, (ii) education and (iii) community use. The ASA is the final arbiter of whether any particular observatory is so designated. ... Upon receipt of your application form, your observatory will be entered on a list of "Pending Designated Observatories" on the ASA Home Page. ... It will be emailed for you. ... Email . ...

... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

GrIm II . ... The MC has been modified to change the way GRIM images are stored to disk when FITS format is selected. ... The solution the Grim team has come up with is to internally add a constant of 10000 to every pixel of the 'bias subtracted' grim image which makes it conform to the unsigned 16-bit number standard, in that all pixel values after this addition of 10000 are in the range 0-65535. ... We have now implemented this for storage of GRIM files in FITS format. ... filetype fits . ...

... 18sep08: bias for 3a/3b changed. Look at p2030 data (polA,polB summed) . 21sep08: bias for all beams changed. ... The wapps in 3 level mode take 100 MHz bw with 64usec sampling and 256 lags. alfa is centred at 1440 Mhz with the 100 Mhz 1390-1490 filter int. The total power was computed and then averaged to .1 seconds. ... Beam 6b is dead and p2030 is adding polA + polB. ... The a2010 data taken on 21sep08 was analyzed to check the stability of all the beams after the bias changes in alfa. ...
