List of current info on visible-wavelength magnitudes of our targets. Corrections and suggestions are welcome! The order here is the order in which the comets were observed with Spitzer. Columns: (1) name, (2) priority, (3) last report, (4) source of info. The priority is either '1' '2' or '3' -- which '1' being the highest priority. '1' implies we have not much solid info at all on the nucleus's magnitude. '2' implies we have some info but followup would be good to get another data point. '3' implies we have high quality results from the literature or from our ground-based observing team and the comet probably does not need to be shot again. "Last report" indicates some basic info on the activity/detectability. "Source" gives the source of the info we have; codes are as used in Lamy et al. 2005, in Comets II, pp. 223-264, and also as follows: AS2 = Fitzsimmons, Nov/Dec 2005, Gemini queue obs.; JMB1 = Bauer, Aug 06, Hale 5-m; KJM1 = Meech, Apr 07, SOAR 4-m; YRF1 = Fernandez, May 07, NTT 3.5m; AS1 = Fitzsimmons, May 07, WHT 4.2-m; KJM2 = Meech, Jun 07, Keck I. JL1 = Licandro, Jul 07, NOT.
