Optical Filters . WFPC2 features two solar-blind Wood's filters, for FUV (<2000 ) imaging. ... These Wood's filters have a broad bandpass from 1200 to 2100 with visible-light transmission lower than 10^-8. ... In such cases, a Wood's filter (or "solar blind" detector as on STIS) is essential for FUV imaging so that the visible light leak does not dominate the observation. ... Two similar Wood's filters (F160AW and F160BW) were mounted in SOFA wheel 1 to provide some redundancy. ...

grdfft - Perform mathematical operations on grdfiles in the frequency domain grdfft in _ grdfile -G out _ grdfile [ -A azimuth ] [ -C zlevel ] [ -D [ scale |g ] ] [ -E [ x|y ][ w ] ] [ -F [ x | ... The horizontal dimensions of the grdfiles are assumed to be in meters. ... Append a scale to multiply by (kr * scale ) instead. Alternatively, append g to indicate that your data are geoid heights in meters and output should be gravity anomalies in mGal. Default is no scale]. ...

Setting Up the IF/LO . ... To choose which IF path to take as well as where to place the LO (high or low side), we've developed an algorithm for the telescope control gui to follow. ... center,highest = the highest band central frequency . ... If the high option does give an LO frequency which lies within another subcorrelator band above the subcorrelator of interest, then check if the low option gives an LO frequency which lies within another subcorrelator band below the subcorrelator of interest. ...

... In some cases where memory space is at a premium, it is possible to tailor the configuration to remove such features as reference clock driver support, debugging support, and so forth. ... The following lines are used in this file: . ... The DEFS_LOCAL line defines global flags that apply to all machines.

ARCSAT ID NUMBER: AS10 DESCRIPTIVE TITLE: A New Filter to Study Stellar Populations. ... BRIEF SCIENCE JUSTIFICATION: We propose to use a newly designed filter (named W: 845-880-nm) to measure the [ЮБ/Fe] ratio in red giants and trace the chemical evolution of stars in the Milky Wayт??s globular clusters, halo and Local Group galaxies. ... We will use the newly-acquired 2т??x2т?? filter from Manastash Ridge Observatory to start observing globular clusters. ...
