STD: 0.00 and MAD:9999.00 in K-band wavelength calibration with neon lamp frames

[masato....@gmail.com]

I'm reducing a K-band mask by following the steps written in "K_driver.py".

When I run the command

Wavelength.apply_interactive(maskname, band, waveops, apply=obsfiles, to='Ne.txt', neon=True),

it returns STD=0.00 and MAD=9999 for some slits which do not appear strange at all.

Then I looked at each slit in neon frames by running

Wavelength.fit_lambda_interactively(maskname, band, 'Ne.txt', waveops, neon=True),

the interactive window for the slits with MAD=9999 shows no data (https://drive.google.com/file/d/0B_gVuA-qxUHVaXFRTkdpZjFFYmc/edit?usp=sharing), though there is Ne lines in the raw frames.

Do you have any ideas what is the cause of this?

Cheers,
