M1 is the magnetic dipole transition which occurs only between states of the same parity.
E2 is the electric quadrupole transition which occurs only between states of the same parity.
M2 is the magnetic quadrupole transition which occurs only between states of different parities.
M3 is the magnetic octupole transition which occurs only between states of the same parities.
Two-photon transition occurs only between states of the same parity.
Hyperfine-induced transition may occur only in isotopes having non-zero nuclear spin.
Undefined transition type.
M1+E2 is a mix of a magnetic-dipole and an electric-quadrupole transition, both of which occur only between states of the same parity.
The oscillator strength is a dimensionless quantity which for strong lines (both in atoms and in ions) is of the order of unity.
This level/line may not be real.
This level was determined by interpolation or extrapolation of known experimental values or by semiempirical calculation; its absolute accuracy is reflected in the number of significant figures assigned to it.

Theoretical value.
Observed in absorption
Line or feature having large width due to autoionization broadening
Beam-foil measurement
Intensity is shared by several lines
Double line
Broad due to overexposure in the quoted reference
Line position estimated
Very hazy line
Superposed with neighbor line
See the original reference on other issues
Observed value given is actually the Ritz value rounded to 0.1 Å, e.g., Ne I
The relative positions of the levels within such a system are accurate within experimental uncertainties, but no experimental connection between this system and the other levels of the spectrum has been made.
This level may have substantial autoionization rate.
Band head
Blended with another line that may affect the wavelength and intensity
Complex line
Diffuse line
Forbidden line
Transition involving a level of the ground term
Hazy line
Line has hyperfine structure
Identification uncertain
Wavelength smoothed along isoelectronic sequence
Shaded to longer wavelengths
Masked by another line (no wavelength measurement)
Term assignment of the level is questionable
Perturbed by a close line
Asymmetric line
Easily reversed
Shaded to shorter wavelengths
Tentatively classified line.
Unresolved from close line
Wide line
Extrapolated wavelength
This wavelength is calculated on-line. The number of significant digits was obtained assuming the trailing zeros in the energies are insignificant, and thus the real accuracy may be higher.
This wavelength is calculated on-line with a proper account of significant digits
Unknown line type
Somewhat less intensity than the value given
A multiplet in the original compilation has been separated into its component lines and the transition probability was derived from the compiled value assuming spin-orbit coupling. This may decrease the listed accuracy, especially for weaker transitions.
Relative intensities provide a qualitative description of what the emission spectrum of a particular element in a particular (low-density) source looks like. More help.
