      NAME 
      kepclip -- Remove unwanted time ranges from Kepler time series data 
      
      USAGE 
      kepclip infile outfile ranges plot clobber verbose logfile status
 
       PARAMETERS 
      infile = string 
      The name of a
      MAST standard format FITS file containing a Kepler light curve
      within the first data extension. 
      outfile = string 
      The name of the output FITS file with unwanted data removed. 
      ranges = string 
      The user must choose here specific time ranges of data to detrend. Ranges can
      be supplied using one of two methods.
       
	-  Time ranges are supplied as comma-separated pairs of Barycentric Julian 
	Dates (BJDs). Multiple ranges are separated by a semi-colon. An example 
	containing two time ranges is:
 
	'2455012.48517,2455014.50072;2455022.63487,2455025.08231'.
  
	
	 -  The user can provide time ranges within a pre-prepared ascii file containing
	one time range per line, e.g.:
 
	2455012.48517,2455014.50072 
	2455022.63487,2455025.08231 
	etc  
	The file 'arbitraryname.txt' is provided to the task using ranges = 
	@arbitraryname.txt, where the '@' tells the task that a file is being provided.
	Files containing time ranges can be generated manually or with the aid of 
	data inspection using the task keprange.
        
      
      plot = boolean 
      Plot the output data? 
      clobber = boolean (optional) 
      Overwrite the output file? if clobber = no and an existing file has 
      the same name as outfile then the task will stop with an error.  
     verbose = boolean (optional) 
      Print informative messages and warnings to the shell and logfile? 
      logfile = string (optional) 
      Name of the logfile containing error and warning messages.  
      
      status = integer 
      Exit status of the script. It will be non-zero if the task halted with an
      error. This parameter is set by the task and should not be modified by the
      user.  
      
      DESCRIPTION 
     kepclip allows the user to remove unwanted or problematic
      data from specified time ranges. Ranges to be removed are
      provided as pairs of BJDs either as a list or by loading an
      ASCII file of times. The ASCII file can be constructed using
      keprange. 
      
      EXAMPLE
	 
	  - kepclip infile=kplr002436324-2009259160929_llc.fits
	  outfile=output.fits range=@ranges.txt plot=y
	
   
	
      TIME REQUIREMENTS 
      Full completion upon one quarter of Kepler long cadence target using a 3.06 
      GHz Intel Core 2 Duo Mac running OS 10.6.4 takes a few seconds. Running times
      increase by several factors if input data contains NaNs. These will be
      filtered out before task execution. 
      
      
      BUGS AND LIMITATIONS 
      The Kepler PyRAF package is privately-developed software made available to 
      the community through the contributed software page of the GO program at
      http://keplergo.arc.nasa.gov/ContributedSoftware.shtml. It is not an 
      official software product of the Kepler mission. Bugs and errors are not
