Yes, Luis, the meaning of the fields :) Thank you.
Have a nice week!

(Asked by: username_0 on 2021-11-04)

I am working (in fact, trying to work) with TPoint for improving a solar telescope pointing calibration (SST, in Casleo, AR) and stumbled on the input data for INDAT command. SST is a multibeam solar observation telescope with Alt-Az support.
INDAT Observation record Format 4 is described as follows on the documentation:
star "observed" Az/El (°,°)
telescope raw Az/El (°,°)
[up to 2 auxiliary readings]

And the sample file for an AltAz support is mmt.dat, whose heading and 1st observational data row are follows:
!
!  Sample data from the Multiple Mirror Telescope

On the data rows, what would be the "column headers"?

Are you talking about the meaning of this fields?:

**02 59 39.744 +03 53 41.15 -0.00082 -0.0743 B1950 03 01 32.220 +04 04 05.72 23 01**

According to [https://sites.astro.caltech.edu/~srk/TP/Literature/Tpoint\_SunWorks.pdf](https://sites.astro.caltech.edu/%7Esrk/TP/Literature/Tpoint_SunWorks.pdf), they seem to belong to **Observation record format 2** (pag. 18):

* star mean RA/Dec (h,m,s,◦,′,′′, $\mu\_{\alpha}$,$\mu\_{\delta}$,equinox)
* telescope raw RA/Dec (h,m,s,◦,′,′′)
* local apparent sidereal time (h,m)

If you mean this fields:

**+31 41 19.6 1987 07 08 +15.0 734.5 2608.0 0.30**

They seem to be the *run parameters* (pag. 18):

* latitude (◦,′,′′)
* UTC date (y,m,d)
* temperature (◦C)
* pressure (mB)
* height above sea level (metre, default determined from pressure)
* relative humidity (range 0–1, default 0.5)
