...quasi-Keplerian
'Quasi-Keplerian' meaning that velocities in the disk are mainly azimuthal, following Kepler's orbits, with a small radial component.
...grating
The resolving powers shown here are for the short camera and one pixel wide slit.
...file
Flat Field and Arc observations will be defined below.
...sampling
Please refer to Section 2.3.3 for an explanation of the sampling procedure.
...achieved
It will become apparent in the section on data reduction why the pattern object-sky-sky-object was chosen.
...source
This is especially important at infrared wavelengths were the background comes from virtually everywhere and can be stronger than the target source. Note that a black body at room temperature, say 300 K, has its peak intensity in the infrared.
...source
All data presented in this work are from point sources.
...image
For all the data presented here the negative beam can be found 10 rows above the positive beam.
...detrimental
OH emission lines have been eliminated from the spectra when subtracting the background contribution. As we will see below steps will be taken in order to remove the telluric absorption lines as well.
...task
Using the same technique as that used to de-ripple would do. IRFLAT is actually used by the CGS4DR deripple_spectrum task.
...star
Both the cross correlation function and the auto correlation function are non normalized.
...data
That is to say, using the J and K magnitudes in Strom et al. and following Meyer et al.
...respectively
These are the mean uncertainties in the observed 514#514's and 515#515's.
...K
recall that if the T Tauri stars studied here have magnetic fields, as expected, the values found for the veiling underestimate the true veiling.
...one
This is a good aproximation, as long as the the chosen interval is small enough.
...quantities
Valenti et al. valentietal93's accretion rates are in good agreement with those found by Gullbring et al. gulbring and the newest estimation is therefore preferred. Hartigan et al.'s accretion rates differ from the former by about one order of magnitude.
