> # CV, CR etc. are for unfiltered CCD photometry

Those observations were actually unfiltered according to the original 
report:

"Mendicini, Daniel José
Santa Fé, Argentina
C 14-F/7  AP - 7 CCD
photometry diferential-unfiltered
Soft IRIS. Catalogo USNO A2.0"

BUT the problem here is that the identifications are wrong for most of the 
stars and the results are not even close to the V mag. from ASAS in any 
case:

Mendicini data ---------------------------------- ASAS-3 V

1744-06 RS OPH  2453679.535 CV 10.17 MDJ  V= 10.7
1744-06 RS OPH  2453679.535 CB 10.92 MDJ
1744-06 RS OPH  2453679.535 CR 10.12 MDJ
1811-46 RS TEL  2453679.519 CV 10.41 MDJ   V= 9.80
1811-46 RS TEL  2453679.519 CR  9.96 MDJ
1811-46 RS TEL  2453679.519 CB 11.16 MDJ
0106-30  U SCL  2453679.561 CV>16.63 MDJ    V= 15.0
0003-39  V SCL  2453679.549 CV>16.04 MDJ    V= 10.9
0044-35  X SCL  2453679.552 CV>15.11 MDJ    V= 11.67
2106-09 VY AQR  2453679.540 CV>15.82 MDJ   V= 13.8

I also wouldn't use USNO as a source of photometric values having PEP, ASAS 
and everything we already know of. Asking for advice or checking what we are 
doing before flooding the databases with wrong data is always recommended...

Cheers,
Sebastian.
