... Several composite flatfields (superflats) have been generated from all Eng. 4 flatfield observations. After removing the LED pattern, these superflats where used to identify OM bad pixels. These badpixels are real physical pixels, thus include 8x8 subpixels. ... Significant deviations from the median or average values were spotted and flagged as bad pixels. ... 8x8 subpixel negative deviation in slew flatfield . ... bad CCD pixel . any 8x8 subpixel deviation in slew flatfield . ...

. To remove duplicate lines from a file use the command: uniq in_file out_file . uniq searches the in_file for consecutive duplicate lines - a line that is immediately followed by one or more lines that are identical to it - and removes them. The result is an out_file that contains no duplicate lines. Use the sort command if you want to remove duplicate lines that occur in different parts of a file. Examples .

... If two or more spectra have been taken under the same conditions, a very efficient way of removing particle hits from the raw data is to replace pixel values with large deviations from other observations with a local estimator, as done in the command COMBINE/LONG .
