... The fitting package in STSDAS (Space Telescope Science Data Analysis System) relies on two basic techniques (one linear and one non-linear) for fitting functions to data. ... Results show that both methods may generate biased coefficients (at the ~few percent level), and over or under-estimate error bars (at the ~10 percent level), in particular from low signal-to-noise data. ... Function coefficient errors are computed directly from the covariance matrix. ... Abscissa is signal-to-noise. ...

... The compression of iflo/ lband receivers (lband wide , lband narrow) was measured on 29apr03. ... Center a band at 1415 Mhz and pass it through a 5 Mhz IF filter (centered at 260 MHz). ... Center another band at 1350,1330 Mhz. ... The 1350 data was normalized to full scale while the 1415 Mhz data was normalized to medianTsys -1 (so the radar 1350 scale and the 1415 Mhz scale are not the same). ... You can see the double bumps in the faa radar (this is the 1350 then 1330 pulses spaced by 6 usecs). ...

... We can help students grasp the significance of Hubble's extremely keen eye, and learn a bit about angles and math in the process, with the following in-class activity. ... Looking through binoculars or telescopes allows us to magnify a small section of the sky. To measure sizes or distances in that small section, astronomers divide a degree into 60 smaller pieces called arcminutes, and further subdivide minutes into 60 smaller sections called arcseconds. ... 30 feet = . ... 36 seconds . ...
