... 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. ...

... Archives . ... One of the biggest culprits is the unit of energy, [keV], which is 1000 electron Volts, for the energy acquired by an electron when it falls through an electric potential of 1 Volt: . ... Then, a temperature in degrees Kelvin can be written in units of keV by converting it with the formula . ... It is tempting to put the two together and interpret a temperature as a photon energy. ... For example, a 1 keV (temperature) Bremsstrahlung spectrum extends out to 1 keV (photon energy). ...

... The then president of the Society, Mr. Robert Burke, appointed a committee of eight or ten members, most of whom had made smaller mirrors, as an instrument committee, with Mr. Thorpe as chairman. ... Seriously, the best practicable solution seemed to be to build a machine to do the grinding and polishing. ... It was decided to grind the edges of the mirror to make it truly circular, as the rough cast glass was some 3/8 inch longer on one diameter than on the other. ...
