kai.reduce.sky.makesky(files, nite, wave, skyscale=True, raw_dir=None, instrument=instruments.default_inst)

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”)

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, number=3, rejectHsigma=None, raw_dir=None, instrument=instruments.default_inst)

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”)

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)

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)

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

kai.reduce.sky.makesky_lp_fromsci(files, nite, wave, number=3, rejectHsigma=None)

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)

Read in the list of files and rotation angles.
