Comet Afrho Liens
=================

file: 'collection.lblx'
--> Please change the Reference_List entry for the overview document from LID to LIDVID.

Documentation
=============

file:overview.txt
--> Negative geometry not well described in overview.txt. E.g. -9999.99, -99.99, -9.99. Error codes need better explanation - why ingest Afrhos without corresponding geometry?
--> Discrepancy between number of unique comets from the original 'comet name' column (346) and statement in overview.txt (334).
--> Add note about how comet fragments are handled.
--> Add notes when changing data as it appeared in the literature (e.g. consolidation of bandpasses, fixing data with typos in the literature).
--> Add criterion and rationale for what is included in the dataset.
--> Expand the documentation. Particularly give definitions what is meant with eg. Jupiter family comets? E.g. comets with a Tisserand  parameter of, or semi-major axis between... (etc).
--> For what epoch/date is the perhelion distance given? If this information is not known, state that.
--> The last sentence contains a list of items, but there is not "and" before the last item.

Data
====
--> Provenance of negative heliocentric/geocentric distances (189 comets) suggests potential broader collation/ingestion error. Remove entries where the values cannot be found.
--> Possible consolidation of bandpass names (R vs R band vs. R-Band, etc)
--> Inconsistencies and typos in comet names:
----> "29P/Schwassmann-wachmann 1" vs "29P/Schwassmann-Wachmann-1"
----> "137P/Schoemaker Levy 2" -> "137P/Shoemaker Levy 2"
----> "45P/Honda Mrkos Pajdesakova" vs "45P/Honda Mrkos Pajdusakova"
----> "C/2012 K1 (PANSTARRS)" vs "C/2012 K1 (PANSTARRS) " (notice extra space).

--> Orbital branch column should have values of I, O, q, and - but instead has '-', 'I', 'I ' (notice extra space), '0', 'Q', nan, and 'q'. 
----> ‘I ‘: 21P, C/2003 WT42
----> ‘Q’: 54P, 67P
----> NaN: 288P

--> Band names are inconsistent:
----> 'B Bessell' vs 'B-Bessell' (same for R and V)
----> 'R' vs 'R ' (notice extra space)

--> Incorrect input of observing geometry info at array index 2852 (78P/Gehrels 2). r_H = 0.076 au but is 3.076 in literature.

--> Incorrect input of observing geometry info at array index 1183 (45P/H-M-P). Delta = 0.36 au, but Horizon’s delta on the date was ~0.63 au, which means the delta in the original paper is transposed.

--> Incorrect input of observing geometry info at array index 1206 (46P/Wirtanen). Phase = 41.5 deg, but Horizon’s phase on the date was ~12.9 deg, which means the phase in the original paper is in error.
