Module Contents

kai.reduce.sky.makesky(files, nite, wave, dark_frame=None, skyscale=True, raw_dir=None, instrument=instruments.default_inst)[source]

Make short wavelength (not L-band or longer) skies.

Parameters:

fileslist of int: Integer list of the files. Does not require padded zeros.
nitestr: Name for night of observation (e.g.: “nite1”), used as suffix inside the reduce sub-directories.
wavestr: Name for the observation passband (e.g.: “kp”)
dark_framestr, default=None: File name for the dark frame in order to carry out dark correction. If not provided, dark frame is not subtracted and a warning is thrown. Assumes dark file is located under ./calib/darks/
skyscalebool, default=True: Whether or not to scale the sky files to the common median. Turn on for scaling skies before subtraction.
raw_dirstr, optional: Directory where raw files are stored. By default, assumes that raw files are stored in ‘../raw’
instrumentinstruments object, optional: Instrument of data. Default is instruments.default_inst

kai.reduce.sky.makesky_lp(files, nite, wave, dark_frame=None, number=3, rejectHsigma=None, raw_dir=None, instrument=instruments.default_inst)[source]

Make L’ skies by carefully treating the ROTPPOSN angle of the K-mirror. Uses 3 skies combined (set by number keyword).

Parameters:

fileslist of int: Integer list of the files. Does not require padded zeros.
nitestr: Name for night of observation (e.g.: “nite1”), used as suffix inside the reduce sub-directories.
wavestr: Name for the observation passband (e.g.: “lp”)
dark_framestr, default=None: File name for the dark frame in order to carry out dark correction. If not provided, dark frame is not subtracted and a warning is thrown. Assumes dark file is located under ./calib/darks/
numberint, default=3: Number of skies to be combined
rejectHsigmaint, default:None: Flag to pass for rejectHsigma for IRAF imcombine By default, no flags are passed
raw_dirstr, optional: Directory where raw files are stored. By default, assumes that raw files are stored in ‘../raw’
instrumentinstruments object, optional: Instrument of data. Default is instruments.default_inst

kai.reduce.sky.makesky_lp2(files, nite, wave)[source]: Make L’ skies by carefully treating the ROTPPOSN angle of the K-mirror. Uses only 2 skies combined.

kai.reduce.sky.makesky_fromsci(files, nite, wave, instrument=instruments.default_inst)[source]: Make short wavelength (not L-band or longer) skies.

kai.reduce.sky.makesky_lp_fromsci(files, nite, wave, number=3, rejectHsigma=None)[source]: Make L’ skies by carefully treating the ROTPPOSN angle of the K-mirror. Uses 3 skies combined (set by number keyword).

kai.reduce.sky.read_sky_rot_file(sky_rot_file)[source]: Read in the list of files and rotation angles.

kai.reduce.sky.write_sky_rot_file(rawlis, nlis, skyRot)[source]: Write the list of files and rotation angles in Lp. Created to avoid using pyraf which causes issues when dealing with non-fits conforming headers.
