Telluric Standard Search

Content owned by aadamson

Search the Hipparcos catalog for dwarfs close to the specified RA and Dec. See this page for guidance about spectral types, airmass etc.

1. RA:     (e.g. 00:42:44)

2. Dec:     (e.g. 41:16:09)

3. Spectral Type(s):     (e.g. B A0 A1)

4. Observation Duration:   hrs

5. Magnitude Range:      < <

6. Maximum Distance:   degrees

7. Output Sorting:   RA   Distance   Magnitude


1,2. Target coordinates should be J2000 and in sexagesimal format.

3. A space-separated list of the spectral types; an "A" matches all A* type stars, while A2 will only return A2 type stars.

4. If observation duration > 0, return two sets of standards, one for before and one for after the science target.

5. Appropriate magnitudes are converted from the Hipparcos V-band magnitudes using standard dwarf colors. Acceptable filters are V, H, L, and M.

6. Maximum distance for acceptable standards.

Currently searches 18,999 O-K dwarfs.
