Notes. Column headings are: object name; Spitzer AORKEY identification; total duration of all AORs; observation mid-time of the 24 and 70 μm measurements (20YY-MM-DD UT); r: heliocentric distance; Δ: Spitzer-target distance; α: solar phase angle; color-corrected flux density values at MIPS photometer reference wavelengths 23.68 and 71.42 μm, upper limits are 1σ; references. Geometric data were extracted from NASA Horizons (http://ssd.jpl.nasa.gov/horizons.cgi) for the indicated mid-time of the observations.
