MOSFIRE at Keck: NIR imaging with flat calibration.

get_exptime(hdr)[source]

Return exposure time from header (exptime_keyword).

get_filter(hdr)[source]

Return filter name from header; leading segment before underscore.

get_gain(hdr)[source]

Return gain value(s) for the detector/amplifier.

Parameters:

hdr (astropy.io.fits.Header) – FITS header (may be used in subclasses for amp-dependent values).

Returns:

Gain in e-/ADU.

Return type:

float or list

get_number(header)[source]
get_rdnoise(hdr)[source]

Return read noise value(s) for the detector/amplifier.

Parameters:

hdr (astropy.io.fits.Header) – FITS header (may be used in subclasses for amp-dependent values).

Returns:

Read noise in electrons.

Return type:

float or list

get_saturation(hdr)[source]
import_image(filename, amp, log=None)[source]

Load raw multi-extension FITS and return processed CCDData (bias/overscan/trim/gain).

Parameters:

  • filename (str) – Path to raw FITS file.

  • amp (str) – Amplifier identifier (number of extensions).

  • log (ColoredLogger, optional) – Logger for progress.

Returns:

Processed frame in electrons (single combined image).

Return type:

ccdproc.CCDData

raw_format(proc)[source]

Return glob pattern for raw files (e.g. ‘sci_img_*.fits’ or ‘sci_img*[!proc].fits’).
