The Linear Ramp Filters (LRFs) provide a narrow band ( ) imaging capability which is continuously tunable from 3710е to 9762е. These are essentially a collection of narrow band interference filters whose central wavelength varies with position on the filter glass. ... If it is necessary to know which CCD will be used, observers can consult Table 3.7 or Table 3.8 , or use the on-line LRF calculator tool on the WFPC2 WWW pages. ... See Linear Ramp Filters for further details on LRFs.) ...

... The file lpf_coefficients.txt , which is created automatically as part of the filter generator's output, contains the actual values of the low-pass filter coefficients. ... The file contains a few comments about the filter in lines beginning with a "#". ... In the hardware, the gain of the filter is scaled by the "gain" comment at the beginning of the file (about 1.05) to accommodate for the window function and the truncated sin(x)/x to give a mean gain of 1.0 for the filter. ...

... Building subroutine libraries . ... This was particularly useful for providing global variables through COMMON blocks. ... Therefore there is a distintion between private COMMON (seen only by the subroutine library) and global COMMON, but this is a semantic distinction only. ... The distinction between private and global variables remains, but, in principle, there is a more legitiamte way to export "global" varaibles from a subroutine library than simply making the INCLUDE file globally visible. ...
