Talk:1956-10-22 54 13

I see some discrepancies between the shotgun coordinates and the ones the peroon map shows using the Meetup_graticule template. And it kind of surprised me since it doesn't happens in the other retro hash I did (which is not so old).

I finally found out what happens. According to shotgun and some .csv file I downloaded from somewhere in the wiki (but now I cannot remember from ¿^^) called "allcordsW30.csv" the value of the DJIA for 1950-08-23 was 220.21, which concatenated with the date: "1950-08-23-220.21" gives the coordinates I searched for: "0.2472169414370836 0.9178578869833560" and that shotgun shows.

However, the geo.crox.net data shows 219.79 (for 1950-08-23), which is, according to shotgun and the .csv file the DJIA data for 1950-08-24... One day off. And "1950-08-23-219.79" gives the point shown in the map.

Is this a known issue I didn't find in any talk page on the wiki?

Was I blinded by science?

Alternate location

On the other hand, I see some expeditions which show a blue pin with an alternate location. How can this be done? I saw nothing on the Template and it is commented on Expedition but I see no example...
