kepmask: plot, create or edit custom target masks for target pixel files¶
kepmask(infile, frameno=100, maskfile='maskfile.txt', plotfile='kepmask.png', imin=None, imax=None, iscale='linear', cmap='bone', verbose=False, logfile='kepmask.log')¶
kepmask - plots, creates or edits custom target masks for target pixel files.
The product from this task is a target mask definition file which can be used by kepextract to extract a light curve from target pixel data. This tool is a GUI interface for defining a pixel mask by moving a mouse over image pixels and selecting them by pressing the left-button of your mouse/keypad.
infile : str
The name of a target pixel file from the MAST Kepler archive, containing a standard mask definition image in the second data extension.
frameno : int
Frame number in the target pixel file.
maskfile : str
The name of an ASCII mask definition file. This is either the name of a file to be plotted, a file to be created, or a file to be edited.
plotfile : str
The name of a PNG plot file containing a record of the mask defined or uploaded by this task.
imin : float or None
Minimum intensity value (in electrons per cadence) for the image display. The default minimum intensity level is the median of the faintest 10% of pixels in the image.
imax : float or None
Maximum intensity value (in electrons per cadence) for the image display. The default maximum intensity level is the median of the brightest 10% of pixels in the image.
iscale : str
Type of intensity scaling for the image display. * linear * log * sqrt
cmap : str
Color intensity scheme for the image display.
verbose : bool
Print informative messages and warnings to the shell and logfile?
logfile : str
Name of the logfile containing error and warning messages.
