The main source is: "Obrona Warszawy w 1939. Wybór dokumentów wojskowych", MON, Warszawa 1968, by Mieczysław Ciepielewicz, p. 88-90 (as on 13 IX 39). This is fundamenal work - there are all survived reports by K. Baran and other commandes from defence of Warsaw in 1939. Very good, solid work.
There is such: "Meldunek sytuacyjny dowódcy obrony przeciwlotniczej czynnej płk K. Barana", including daily report as on 13 IX 1939, and for the next days too, but there are not all reports for all days in IX 39 (like for 25-27 IX - pity), not all survived in our archive.
Next, there are 2 texts from 70. done by St. Truszkowski about Polish A/A batteries in IX 1939. The maps are based on his material, which is given under the map.
Next there are 4 big volumes of all reports, documents, memories done in WW II or after by Polish A/A commanders, who fought in IX 1939: "Polska obrona przeciwlotnicza 1939. Opracowania i dokumenty. tom 3/1, 3/2, 3/3, 3/4, Warszawa 2012-2013. There are almost all reports of Polish A/A commanders taken from the all archives public, private in Wasaw, London, publication ect., including materials from the defence of Warsaw.
This text (mine) it is as for such artcle quite large (about 85.000 signes) but I can not make it much bigger, such things like giving the Luftwaffe's unit names is too much for such small space in magazine. Sorry.
Greg you can do this if you want and you can find this LW's unit. Emmerling's books have this info. (vol. 2 and vol 3). It is easy, "a piece of cake". To work!
This text is in: Historia Wojsko i Technika, wrzesień-październik, nr 1/2015, "Obrona przeciwlotnicza czynna Warszawy w 1939 r.", p. 32-47, 30 b&w photos, 3 maps, 1 colour drawing.
Next, there is a nice text done by M. Emmerling, "Dywizjon niszczycieli I./76 w 1939 roku", p. 48-69 too. This is quite strong magazin with articles about IX 1939 in/over Poland,
