slit position x: position of a slit in center1000.2bin read-out mode (100-500)
Grism: no2
Slit Position: x=200 (in center1000.2bin)
| CCD X | λ (Å) |
|---|---|
| 1 | 5247 |
| 1000 | 9030 |
Bad Columns:
x=403 to 407 (in spec.2bin)
λ = 6560 to 6575 (approx.)
Note: the relation between ccd x-position and wavelength depends on the position of the slit, and the wavelengths calculated by this script are not accurate; the accuracy is typically ∼10Å and the error can be as large as ∼50Å.
