The malloc failure for BPASS is gone (thanks) but now I am struggling with the fact that no matter what i do I seem to have
a mystery end channel that gets a huge number thrown in for the BPASS solutions. I tried flagging and uvcop to get rid of this but no matter how I cut my data the last channel always has high values. Example below. This is still on Hamal, and user 1014, disk 1
file 3 or 4 (VLITE data) or HAMAL user 1013, disk 1, file 14 (WIDAR data).
VLITE example:
hamal > BPASS1: 284 2.93 3.96 1.24 1.65 0
hamal > BPASS1: 285 3.05 3.90 1.37 1.87 0
hamal > BPASS1: 286 2.32 3.12 1.35 1.78 0
hamal > BPASS1: 287 2.88 3.86 1.46 1.88 0
hamal > BPASS1: 289 2670.65 6504.54 89.64 113.05 0
hamal > BPASS1: BASOLV: 14 flagged channels in IF 1
hamal > BPASS1: BASOLV: will attempt to interpolate across band
hamal > BPASS1: Closure error statistics: IF 1 correlator 2
hamal > BPASS1: Channel Mean amp & amp**2 Mean phase & phase**2 Excess
hamal > BPASS1: 1 3.90 5.14 1.95 3.10 0
hamal > BPASS1: 3 4.29 5.43 1.89 2.85 0
hamal > BPASS1: 4 4.38 5.54 2.16 3.11 0
hamal > BPASS1: 5 4.48 5.52 2.14 3.14 0
hamal > BPASS1: 6 4.99 6.58 2.40 3.53 0
--------
WIDAR example:
BPASS2: 472 10.44 13.80 7.35 9.42 0
hamal > BPASS2: 473 12.97 16.11 8.41 10.70 0
hamal > BPASS2: 474 11.73 14.64 7.26 9.04 0
hamal > BPASS2: 475 8.09 10.46 3.94 5.39 0
hamal > BPASS2: 512 6684503.00********** 0.03 0.04 0
hamal > BPASS2: BASOLV: 8 flagged channels in IF 1
