... The software was originally developed as a set of Fortran routines which were available both as stand-alone executables and as IRAF tasks in the Dither package. ... This set of code formed the basis for a more automated task for aligning images to produce distortion-corrected images; namely, the Python task PyDrizzle (Section 5.3) . Finally, all the steps required to identify cosmic rays using the aligned images produced by PyDrizzle were automated in the Python task MultiDrizzle (Section 5.4) . ...

... Series 4000 filters thread into the barrels of virtually all 1.25" eyepiece brands. Meade Series 4000 filters are a large 26mm in clear aperture and are manufactured from the purest crown optical glass, dyed-in-the-mass ( not "color coated"); there are no finer filters available for telescopic applications. ... For visual applications Series 4000 filters thread into the barrels of all Meade 1.25" eyepieces, and into the barrels of virtually all other 1.25" eyepiece brands as well. ... Meade 4M | ...

... The third processing stage filters the combined event list to produce the filtered event list, which contains the collection of node-specific exposure maps. ... Combining the event filtering with exposure map construction in one step assures mutual consistency. ... If the original combined event list is missing (as, for example, in the PPS) the original filtered event list is acceptable as a substitute if no changes have been made to the original attitude and housekeeping GTI. ...
