Exoplanet:	HD189733 b
observer:
Post address:
E-mail:
Station:
Geographic location:	east longitude: 15° \| north latitude: 38°
Instrument:
Photometric filter:	U B V R I Clear
Notes / conditions:	The data from 42nd were shifted of 0.007 mag. to fix the photometric effect due to the telescope inversion (see the original data on the attached image of the stellar field). Exp.: 200s, binning 1 CCT Temp.: -13 °C Sky: clear, with Moon and strong light pollution. To avoid direct Moon Light a particular hood was used.

object HD189733 b

Gerold Holtkamp, 25. 9. 2022
Gerold Holtkamp: The description for "Photometric filter" and "Notes/Comments" went wrong. Correct is: Photometric filter is "Clear". I used Antlia L-filter which is not equal to V-Sloan-Filter.

This analysis should replace the old AXA analysis present on TRESCA database (see HD189733 - Marino - AXA - 2008-09-07).
