Jeff mock supplied 6 different types of filters to use with the high resolution mode of the mock spectrometer. ... Plots were made of the time domain voltage response as well as the frequency domain power response. A decimation of 10 was used for the filter decimation. this gave a filter length of 80 coeff. The plots compare the filter shapes for these filter types (.ps) ( .pdf ) . ... Each color is a different filter type . middle: spectral density reponse for each filter . ...

... The photometric accuracy of the data is often limited by the quality of the flatfield used to calibrate the data (see "Determining the "Best" Reference Files" on page 45-14 as well as the WWW Reference File and Closure Flat Memos). ... Large gradients caused by F122M. Due to the Earth's albedo, some broadband filters had to be taken in conjunction with a neutral density filter (either F8ND or F122M) to obtain sufficient numbers of unsaturated earthflat observations for creating reference files. ...

Classroom Activity: Making a Rainbow . ... When white light from the Sun or a light bulb passes through a prism, the light splits into its component wavelengths. ... Red, blue, green colored filters - if possible, cut 1x4-inch pieces of the filters for each student . ... Many students have the misconception that filters somehow dye the light a certain color. ... Younger students can draw the rainbow and make up a mnemonic for remembering the order of the colors (such as, ROY G. BIV). ...

Next: Data Acquisition Up: CCD Systems and Previous: The ST-4 . One SBIG upgrade from the ST-4 is the ST-6. ... This system also uses a motorized filter wheel made by Compuscope. ... The TEC for this camera head is similar in operation to that of the Lynxx, however the ST-6 allows the temperature to be set. ... Used together with the ST-4, longer uninterrupted exposures are possible. ... A function in the software allows the operator to combine several short exposures to create a composite image. ...
