# VP_No - participant number
# Kommentar - comment of the experimenter
# Index - can the data be used in the analysis? -> 0 = yes, 9 = no, 1 = under certain circumstances
# Timestamp - start of the first condition of the experiment
# Gender - gender of participant -> 1 = male; 2 = female; 3 = non-binary
# Age - age of the particiant
# Experience - does this participant have previous experience with VR? -> 1 = no, 2 = yes
# Glasses - does the participant have a visual impairment (do they normally need glasses/contact lenses)? -> 1 = yes, 2 = no 
# MISC_01_Pre_RFT - German translation of the 11-point Misery Scale, asked before the RFT condition of the experiment
# MISC_02_Post_RFT - German translation of the 11-point Misery Scale, asked after the RFT condition of the experiment
# MISC_03_City_Min_2, MISC_04_City_Min_4, MISC_05_City_Min_6, MISC_06_City_Min_8, MISC_07_City_Min_10 - German translation of the 11-point Misery Scale, asked during the city condition in the experiment (after 2, 4, 6, 8 and 10 minutes respectively)
# VRSQ_Pre_RFT_0x (VRSQ_Pre_RFT_01 to VRSQ_Pre_RFT_09) - German translations of the questions from the Virtual Reality Sickness Questionaire, asked before the RFT condition of the experiment 
# VRSQ_Post_RFT_0x (VRSQ_Post_RFT_01 to VRSQ_Post_RFT_09)- German translations of the questions from the Virtual Reality Sickness Questionaire, asked after the RFT condition of the experiment 
# VRSQ_Post_City_0x (VRSQ_Post_City_01 to VRSQ_Post_City_09) - German translations of the questions from the Virtual Reality Sickness Questionaire, asked after the City condition of the experiment 

the unfiltered data also contains additional variables, most of which have been excluded from the filtered data because of problems which make it hard to use these: 
# Sum_Checkpoint - how many checkpoints has the participant reached? (could be used in analysis)
# Experience_h - if the participant has previous experience with VR, how much? -> unfortunately the coding is no longer clearly traceable (therefore not that usefull)
# Experience_Studies - has the participant participated in one of the previous studies about that topic? -> unfortunately the coding is no longer clearly traceable (therefore not that usefull)
# there are a lot of variables named some variation of "Tx_Test_Frame" oder "T_Frame" which unfortunaltely also cannot be used
