1. M1 Airflow Lab Tests
... A three-cell test section roughly representative of the primary mirror was provided for this test by the Steward Mirror Lab. ... Additionally, the tests are intended to determine relative airflow vs. pressure drop characteristics for each of the air flow patterns so the results can be evaluated both as a function of flow rate and of pressure drop along the flow path. ... The bottom (top as installed) was cut out so it could close the chamber for heating and be removed for the cooling tests. ...

... Analysis of the UVIS03 data show that the gain ratios, relative to the nominal 1.5 , are 1.01-1.04, 2.09-2.15, and 4.28-4.39 at a detector temperature of -82C. A check of the absolute gain of the nominal 1.5 setting was performed using flatfields from the linearity (UVIS05) test; gains were measured at 1.53, 1.52, 1.56, and 1.55, with errors 0.01 , for quadrants A,B,C, and D. Introduction The purpose of the ... Gain ratios for the four quadrants, relative to gain 1.5. ...

... 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). ...

20. Relative pathnames
. You can define a file or directory by its location in relation to your current directory . The pathname is given as / (slash) separated list of the directories on the route to the file (or directory) from your current directory. A .. (dot dot) is used to represent the directory immediately above the current directory. In all shells except the Bourne shell, the ~ (tilde) character can be used as shorthand for the full pathname to your home directory. Examples . Did You Know? .
