[vsnet-campaign-sn2002ap 180] My final near-IR magnitudes (2002. Feb 1. and 2.)
As I had one photometric night, I also provide magnitudes for two
nearby stars (S1 and S2). Coordinates are based on my own astrometry
(USNO reference frame):
SN: 01:36:23.917 +15:45:13.35 (J2000)
S1: 01:36:32.052 +15:45:07.91 (J2000, USNO U1050_00440282)
S2: 01:36:27.383 +15:46:30.19 (J2000, USNO U1050_00439915)
2002. Feb. 1. (photometric):
K-prime: 19:33:42-19:40:00 (UT)
J: 19:41:49-19:48:05 (UT)
Object J K-prime
S1 10.40 9.61
S2 12.37 11.96
SN 12.61 12.45
---------
2002. Feb. 2. (non photometric, calibrated through the two reference stars):
K-prime: 19:48:24-19:54:45 (UT)
J: 19:55:20-20:01:37 (UT)
Object J K-prime
S1 10.40 9.63
S2 12.37 11.94
SN 12.46 12.22
If someone is interested in the data:

See NOTES.sn2002ap for a bit more info on calibrations, sn2002ap.ps for
a finding chart (North up, West right).
Data were taken using the Calar Alto 3.5m telescope and the Omega-Prime
near-IR imager. Effective exposure time was 5 minutes (5 dithering
positions, 30 exposures in each, 2sec exposures). Calibration accuracy
is unknow at this moment, probably around 5%.
I'm the PI (Gyula P. Szokoly), Carmen Schmitt was helping with the
observations. Data on the web-site are public domain (see above).
