class
mpdaf.drs.Channel(extname, filename)[source]¶ Bases:
objectChannel object corresponds to an extension of a MUSE raw FITS file.
Parameters: - extname : str
The extension name.
- filename : str
The raw FITS file name.
Attributes: - extname : str
The extension name
- header :
astropy.io.fits.Header The extension header
- nx : int
Lengths of data in X
- ny : int
Lengths of data in Y
- mask : array of bool
Arrays that contents TRUE for overscanned pixels, FALSE for the others.
Methods Summary
get_bias_level(det_out)computes median value of the overscanned pixels. get_image([det_out, bias])Return an Image object. get_image_just_overscan([det_out])Return an Image object in which only overscanned pixels are not masked. get_image_mask_overscan([det_out])Return an Image object in which overscanned pixels are masked. get_trimmed_image([det_out, bias])Return an Image object without over scanned pixels. overscan([copy])Return a masked array where only overscan pixels are not masked. trimmed([copy])Return a masked array where overscan pixels are masked. Methods Documentation
-
get_bias_level(det_out)[source]¶ computes median value of the overscanned pixels.
Parameters: - det_out : int in [1,4]
Number of detector taken into account.
Returns: - out : float
-
get_image(det_out=None, bias=False)[source]¶ Return an Image object.
Parameters: - det_out : int in [1,4]
Number of output detector. If None, all image is returned.
- bias : bool
If True, median value of the overscanned pixels is subtracted.
Returns: - out :
Image
-
get_image_just_overscan(det_out=None)[source]¶ Return an Image object in which only overscanned pixels are not masked.
Parameters: - det_out : int in [1,4]
Number of output detector. If None, all image is returned.
Returns: - out :
Image
-
get_image_mask_overscan(det_out=None)[source]¶ Return an Image object in which overscanned pixels are masked.
Parameters: - det_out : int in [1,4]
Number of output detector. If None, all image is returned.
Returns: - out :
Image
