6.1 Zhurnal nablyudenii
Kogda vy naveli teleskop na zvezdu i fotometr gotov vydat' sootvetstvuyushie otschety, neobhodimo byt' gotovym zafiksirovat' rezul'taty v sootvetstvuyushei forme. Pri provedenii kazhdogo izmereniya nuzhno zaregistrirovat' nomer ili inoe identifikacionnoe nazvanie ob'ekta, vremya, sootvetstvuyushee seredine ekspozicii v kazhdoi polose, nomer ili naimenovanie etoi polosy, i sobstvenno otschety, sootvetstvuyushie svetovomu potoku ot izmeryaemogo ob'ekta. Krome togo, v nachale raboty i pri kazhdom izmenenii rezhima neobhodimo ukazat' kto provodit nablyudeniya, po kakoi programme, na kakom teleskope i s kakim fotometrom provodyatsya izmereniya, kakaya segodnya kalendarnaya data, kakov razmer diafragmy fotometra, kakova temperatura okruzhayushego vozduha, kak vy ocenivaete sostoyanie prozrachnosti atmosfery i pr.
Eti dannye sosredotochivayutsya v tablice, kotoruyu obychno nazyvayut zhurnalom nablyudenii. Do nedavnego vremeni zhurnaly nablyudenii v samom dele predstavlyali iz sebya tolstye tetradi, v kotorye karandashom zapisyvalis' perechislennye svedeniya. Pri provedenii nablyudenii na avtomatizirovannyh fotometricheskih kompleksah podobnaya tablica indiciruetsya na ekrane upravlyayushego terminal'nogo ustroistva i zapisyvaetsya v pamyat' EVM.
V Tablice 6.1 priveden primer zhurnala nablyudenii na odnokanal'nom
fotometre v ruchnom rezhime.
29 sentyabrya 1990 goda.
UT = 1510. Tyan'-Shan'skaya vysokogornaya observatoriya GAISh, teleskop AZT-14 (zapadnyi), = 48 sm.
Odnokanal'nyi fotometr WBVR, chastotomer Ch3-54, usilitel' sistemy Kolpakova-Magnickogo
Nablyudateli: V.G.Moshkalev (navodit teleskop), O.M.Kolyhalova (spisyvaet dannye s tablo chastotomera v tetrad')
Vremya nakopleniya odnogo otscheta 10 sekund. Delaem, kak pravilo, po dva otscheta v kazhdom fil'tre.
Programma: peremennye zvezdy.
Apparatura vklyuchena na progrev v UT = 1430.
Yasno. V sumerkah koe-gde byli legkie peristye oblaka, kotorye zatem ischezli. Davlenie 550mmrt.st., temperatura +4 C.
1527 Luna eshe ne zashla.
1615 Nachalo nablyudenii peremennoi zvezdy HD 187764.
Teleskop v perekladke "k vostoku ot kolonny".

Konec nablyudenii HD 187764
Vse skazannoe o zhurnale nablyudenii mozhet pokazat'sya trivial'nym i nenuzhnym na etih stranicah, odnako praktika pokazyvaet, chto nablyudateli, dazhe obladayushie opredelennym opytom, chasto greshat nepolnotoi zapisei v zhurnale. Osobenno bol'shoi vred nanosit takaya nepolnota togda, kogda obrabotku vypolnyaet drugoi chelovek i cherez znachitel'noe vremya posle nablyudenii. A potom vyyasnyaetsya, chto data ne zapisana...
V tabl. 6.2 priveden primer zhurnala nablyudenii, kotoryi stroitsya v poluavtomaticheskom rezhime na fotometricheskom komplekse AFK-2. Etot kompleks budet opisan v gl.VII. V tablice primechanie ``E'' v pervoi stroke nablyudenii oznachaet, chto truba teleskopa nahoditsya v vostoku ot kolonny, a znachok # posle nomera vezde oznachaet, chto izmeryaetsya fon okolo zvezdy, nomer kotoroi priveden. Znak * v nachale stroki oznachaet, chto eto stroka primechanii. Posle kazhdogo otscheta sleduet chislo, harakterizuyushee ego otnositel'nuyu srednekvadraticheskuyu oshibku za vremya nakopleniya (v promilyah).
