This text data file (.csv) contains the outputs of two stereological readings, done by three agents for 15 slides, and by two agents for 20 slides. The information contained in this table is as follows: o agent: code id for the three agents that did the calibration exercise (A, B and C) o num_fish: fish number for this study. Here we have 20 different fish o fish_id: identification number of the fish. This id number is identical to the name given to the pictures of the full ovaries (Full_Ovaries_Data) o scan_id: identification number of the digitized histological slide that was used for the stereological count (Stereology_Readings_Data / Interagent_Calibration) o total_points: total number of identified structures for the stereological sampling grid of a slide o hit_points: number of time a structure has been counted on a single slide o Fract_estim: percentage (%) of times a structure was counted on a single slide = (100 / total_point) * hit_points o reading: reading number. In this study, we have two readings, the first (1) and the second (2) o cell-type: abbreviation of the structure identified (lexicon available here: https://archimer.ifremer.fr/doc/00501/61234/66069.pdf). In this study, there are 20 different structures: + ov : Oogonium + op1 : Premature stage 1 oocyte + op2 : Premature stage 2 oocyte + oca : Cortical alveoli oocyte + vit1 : Oocyte in early vitellogenesis + vit2: Oocyte in vitellogenesis with nucleus migration + vit3 : Oocyte in vitellogenesis with zona pellucida growth + vit4 : Oocyte at the end of vitellogenesis + och : Oocyte in hydration + oh : Hydrated oocyte + POF : Post-Ovulatory Follicle + oaA : Oocyte in Alpha atresia + oaB : Oocyte in Beta atresia + L : Lysis + tc : Connective tissue + pg : Gonadal wall + cs : Blood vessel + ei : Intercellular space + v : Unnatural emptiness + i : Undetermined
