 ### Data Fields
 
-[More Information Needed]
+CSV Columns are as follows:
+
+- `CAMID`: Unique identifier for each specimen that was photographed. Each `CAMID` corresponds to multiple images (based on factors such as `View` and `file_type`).
+- `X`: Unique identifier for each line in the master CSV.
+- `Image_name`: Filename of image.
+- `View`: View of the butterfly in the image: `dorsal`, `ventral`, `forewing dorsal`, `hindwing dorsal`, `forewing ventral`, `hindwing ventral`, `dorsal and ventral`.
+- `zenodo_name`: Name of the CSV file with metadata used to populate this file from the associated Zenodo record.
+- `zenodo_link`: URL for the Zenodo record of the image.
+- `Sequence`: Mostly numeric IDs, not unique, please see the associated Zenodo record for more information on the meaning of these designations.
+- `Taxonomic_Name`: Indication of the Genus, Species, and possibly, subspecies, of the specimen. For Cross Types, this is just the Genus species pair (all _Heliconius erato_ or _Heliconius melpomene_).
+- `Locality`: Likely location of specimen collection, varying levels of specificity. Please see the associated Zenodo record for more information on the meaning of these designations.
+- `Sample_accession`: Some type of ID, not unique, please see the associated Zenodo record for more information on the meaning of these designations.
+- `Collected_by`: Abbreviations (likely for those collecting the specimen), please see the associated Zenodo record for more information on the meaning of these designations.
+- `Other_ID`: Mostly numeric IDs, not unique, please see the associated Zenodo record for more information on the meaning of these designations.
+- `Date`: Please see the associated Zenodo record for more information on the meaning of these designations.
+- `Dataset`: Overall collection the images belong to: `Heliconiine Butterfly Collection Records from University of Cambridge` (largely, but not entirely Heliconius), `Patricio Salazar`, `Nadeau Sheffield`, `Bogota Collection (Camilo Salazar)`, `Cambridge Collection`, `Mallet`, `Merril_Gamboa`, `STRI Collection (Owen)`. Please see the associated Zenodo record for more information on the meaning of these designations.
+- `Store`: Storage location for specimen (`Box ###`).
+- `Brood`: Likely indicator of batch of butterflies. Please see the associated Zenodo record for more information on the meaning of these designations.
+- `Death_Date`: Date of specimen death. Only noted for 318 images.
+- `Cross_Type`: Laboratory cross breeding information. There is a mix of F1 (subspecies x subspecies), F2 (F1 x F1), and backcross (F1 x subspecies) hybrids. Generally, the order of the subspecies listed in the cross corresponds to the sexes of the parents (Maternal x Paternal). There are approximately 5,000 such images; on average, there are both raw and jpg images of the specimens for each view, so this covers 820 unique specimens.
+- `Stage`: Life stage of the specimen. Only 15 specimens have a non-null value for this feature, and they are all labeled as `Adult`.
+- `Sex`: Sex of the specimen: `Male`, `Female`, or `Unknown`.
+- `Unit_Type`: Type of the specimen: `wild`, `reared`, `Mutant`, `Wild`, `e11`, or `e12`. Please see the associated Zenodo record for more information on the meaning of these designations. 
+- `file_type`: Image type: `jpg`, `raw` (.CR2), or `tif`.
+- `record_number`: The number associated with the Zenodo record that the image came from.
+- `species`: Species of the specimen. There are 246 species represented in the full collection, 37 of these are species of Heliconius.
+- `subspecies`: Subspecies of the specimen (where available, mostly labeled for Heliconius). There are 155 subspecies represented in the full collection, 110 of which are Heliconius subspecies.
+- `genus`: Genus of the specimen. There are 94 unique genera represented in the full collection.
+
+**Note:**
+ - `Jiggins_Heliconius_Master.csv` has all but the `genus` column, since all images are Heliconius.
+ - `Jiggins_Zenodo_dorsal_Img_Master.csv` does not have the last four columns, but they can be added easily with the appropriate functions in `notebooks/standardize_taxa.ipynb`. This file also has a column `CAM_dupe` indicating whether the `CAMID` has multiple images within this subset.
