The log

Other makes of altimeter keep their settings on the device and do not write them into the log, so there are none to show here. This is what the file itself told us.

Getting logs off the Zeta Rocketry Zeta II
Read the flight off the altimeter with ZetaPost and upload the .zta file it saves. It carries the raw pressure and all three accelerometer axes, so the altitude, burnout and thrust are worked out here. The logs we have each hold 36 seconds, so a long descent may end in the log before it lands.

Files

Where the altimeter signs its log, the file carries that signature and a tick beside it. A tick means the data is unchanged since the device wrote it, which is what a record claim needs.

The weather for 48 hours either side of the launch, within 15 km of the launch site: NOAA GFS every hour, at the surface and up to about 31 km, and the NOAA GEFS ensemble where this site holds it.

The log recomputed for your own sea-level pressure and temperature. Columns: time, altitude as recorded and adjusted, raw altitude as recorded and adjusted, pressure.

This file is built here from the signed log, so it carries no signature of its own. Anyone verifying a claim should be sent to the flight page and build their own from the original.

Custom CSVbuilt in your browser
Pick any of the chart’s data sets, the worked-out ones included, and the part of the flight to cover. Values come in the units the chart is set to.

Time span

One row for every time any chosen data set has a sample. A data set with no sample at that time is left blank rather than filled in. Built from the chart’s data, so it carries no signature.
