Instrument Science Report ACS 02-03 RELATIVE GAIN VALUES AMONG THE FOUR WFC AMPLIFIERS R. C. Bohlin, G. Hartig, & Wm. ... Our method relies on the average absolute gain measurements of the four amplifiers but provides a more accurate determination of their relative gains. 1.INTRODUCTION The absolute gain values for the four ACS WFC amplifiers (A, B, C, & D) have been measured by Martel, Hartig, & Sirianni (2001, MHS) with a typical accuracy of 0.6%. ...

GIPSY applications programmers should be aware of the fact that the so called undefined value (or BLANK as it is called in FITS terminology) is a fixed value which can only be different across different computer operating systems. ... The subroutine SETFBLANK can be used to set one value to BLANK; subroutine SETFNBLANK sets a whole array to BLANK. For the sake of speed it is advisable to compare data values directly with the system defined BLANK instead of using the slower function FBLANK. ...

... Since summer 2012 it replaces the MIDAS plot engine which was used in trendPlotter before version 3.0. ... Syntax changes from MIDAS to python: . ... Compute and fit rules (identifies by COMPUTE_RULE and FIT_RULE in the config.tp_ files) have to be rewritten into Python syntax. ... Any Python statement that can be written in one line of code can be used to describe the RULES. ... One can also use multi-valued Python lists to simultaneously plot many lines on a trending plot. ... pylab.plot(ax) . ...

DIGITAL WDC EXCHANGE FORMAT . FOR OBSERVATORY 1.0 MINUTE VALUES 1. ... DATA-1 .. DATA-60 are 1-minute values of the given element for that hour. ... Typically, digital 1-minute values received by WDCs from organizations operating automatic magnetic observatory instruments are averages of more frequendy sampled values, e.g. 10-second point samples. ... If the method used to obtain 1-minute average values is important to a user, the WDC will assist in determining the exact procedure applied. ...

This widget allows you to offset the telescope. ... Offset type : one of "Object Arc", "Object Arc XY" or "Boresight". ... This is motion on the sky or instrument, so don't worry about cos(dec). ... If you want to move that point (e.g. center your object along a different bit of the slit), then use a boresight offset. ... Note that a +X object xy offset will move the sky in the -X direction on the focal plane, because you are centering something in the +X direction on the boresight. ...

... Optical characteristics of amorphous SiO 2 in the region 1400-200 cm -1 . ... Optical constants: . amorphous SiO 2 Some details: . Reflectance of polarized radiation at the incidence angle 12 deg was measured in the range from 1400 to 200 cm -1 for several samples of amorphous SiO 2 . Special technique applied allowed to reduce the relative errors downto 1% for the reflectance values of 0.005-0.8. The optical constants were obtained by the Kramers-Kronig method. ...

By comparing several restrictions of Siegel-Eisenstein series of degree 3, B.Heim recently found a remarkable (and somewhat mysterious) formula relating central values of triple L-functions to other critical values. It is quite common that such formulas can be generalized by using equivariant di ential operators. ...

... This plug-in enables you to add various types of lighting effects to your (RGB) image. ... Directional light . ... Well, you get the idea :) The default settings for this light-type is [-0.5,-0.5,-1.0]. ... Higher values makes your image reflect a lot of light (appear lighter or more intense), while smaller values makes it appear more dull or matte. ... A value of 1.0 makes your image very shiny (bright high-lights) while smaller values makes you image less shiny, making the high-lights dimmer. ...
