Source discrepancies

What the warehouse found when it checked this series: the same figure from two agencies, splice overlaps, published rates against ones recalculated from the index, and outliers.

Error in the source6 Oct 2015
This series reads 97.37; the same figure from the other source reads 109. Compared with LK.EXT.FX_DAILY_TT.AUD.BUY.D.

Two agencies: 109.01 and 97.37, difference 11.64.
LK.EXT.FX_DAILY_TT.AUD.BUY.D: IF_Buying_Selling file vs the Data Library
LK.EXT.FX_DAILY_TT.AUD.BUY.D: value 109.0100 vs Data Library 97.3700. Whole-day anomaly in the source file: every daily-TT currency (buy and sell) jumps on this one day while every neighbouring day matches the Data Library exactly (e.g. USD/BUY 144.53 here vs 138.9x the day before and after, in both the file and the Library) - re-verified series by series. A single bad row in IF_Buying_Selling_Exchange_Rates...xlsx, not a parsing issue.
Error in the source1 Oct 2018
This series reads 119.4; the same figure from the other source reads 120.1. Compared with LK.EXT.FX_DAILY_TT.AUD.BUY.D.

Two agencies: 120.13 and 119.44, difference 0.69.
LK.EXT.FX_DAILY_TT.AUD.BUY.D: IF_Buying_Selling file vs the Data Library
LK.EXT.FX_DAILY_TT.AUD.BUY.D: value 120.1302 vs Data Library 119.4400. USD/BUY 180.08 here vs ~167.0 the day before and after). A single bad row in the source file.
Rounding26 Apr 2018
This series reads 116.6; the same figure from the other source reads 116.7. Compared with LK.EXT.FX_DAILY_TT.AUD.BUY.D.

Two agencies: 116.666 and 116.62, difference 0.046.
LK.EXT.FX_DAILY_TT.AUD.BUY.D: IF_Buying_Selling file vs the Data Library
LK.EXT.FX_DAILY_TT.AUD.BUY.D: value 116.6660 vs Data Library 116.6200. Every currency differs from the Data Library by under 0.2 LKR on this date - the file records 4 decimal places (e.g. USD/BUY 155.5247) where the Library's copy has 2 (155.43); a precision/rounding difference between two CBSL publications of the same TT rate, not an error.

AUD: IF_End_of_the_Month_Exchange_Rates.xlsx (CBSL's IMF/IFS reporting rate) vs the Data Library's daily commercial-bank TT mid on the last business day on record each month. AUD in particular carries a striking one-year anomaly: the file's month-end rate runs about 60 LKR for all twelve months of 2005 while the TT mid on the same days runs 75-88 LKR (~20%), not seen in any other year, currency, or in the Monthly-Average file's own AUD 2005 figures (those track the TT mean-of-month within 0.1 LKR for 11 of 12 months) - and one comparison point on the held side is itself implausible (the Library's AUD daily mid on 2005-12-30 is 0.87 against neighbouring days around 75). Neither file is corrected.
